This is another example of Bambu using corporate posturing and community-friendly language to avoid the real issue.
Disclosure: I wrote this post. I used AI to help organize and insert source links from bookmarks and articles I have been curating since 01/25. The argument, structure, and formatting choices are mine. The use of headings, underlining, links, and nested source sections comes from roughly two decades as a forum user, moderator, and administrator. Any polish in the writing is not because I am a professional writer. It is the byproduct of 40 years of technical, business, and customer-facing writing.
Bambu has the right to control access to its cloud
I will grant Bambu one point up front: Bambu has the right to control access to its own cloud infrastructure. An AGPL license does not give anyone unlimited access to Bambu’s private cloud service. If a third-party client is actually presenting itself to Bambu’s servers as official Bambu Studio, then Bambu has a legitimate basis to object to that specific cloud behavior.
But that narrow point does not resolve the larger problem
Bambu built its early success on enthusiasts and early adopters who believed they were buying products they would own, not renting permission to use those products under whatever access model Bambu might later impose.
Those early users supported Bambu when the company was still earning trust. They reasonably expected normal ownership rights over the printers they paid for, including local workflows and third-party tools without forced dependence on Bambu-controlled middleware.
The 01/16/25 Bambu Connect controversy changed the trust equation
The Bambu Connect controversy was not just a software preference dispute. It changed the after-sale conditions of product use.
Owners were effectively told to choose between firmware improvements and preserving control over their own machines. That is not an acceptable choice. A product owner should not have to freeze firmware to preserve property rights.
Bambu later walked back parts of that position after public outcry, but that does not erase the original direction of travel. The concern was not imagined. Bambu’s own communication created it.
That same pattern is showing up again here.

If this is truly only about cloud impersonation, then prove it clearly
Bambu now says the OrcaSlicer-BambuLab issue is only about cloud impersonation.
Fine.
If that is truly the issue, then publish the technical boundary. Identify the specific behavior that crossed the line. Separate cloud access from LAN/local control. Separate actual server impersonation from restoring functionality owners previously had. Separate copyright claims from contract claims from security claims.
Instead, Bambu has again chosen opacity.
The company makes broad claims about the GitHub project, then reportedly pressures the developer not to reveal the details of Bambu’s demands. That is the heart of the distrust.
If Bambu’s case is as clean as presented, then publish a sanitized technical explanation. Show the exact network behavior being objected to. Explain the exact rule being enforced. Do not ask the community to accept a conclusion while hiding the facts needed to evaluate it.

Bambu benefited from open source when it suited Bambu
This is especially hard to accept from a company that repeatedly presents itself as a supporter of open source.
Bambu benefited from open-source software, open-source culture, and early enthusiast support. Bambu Studio traces its roots through the open-source slicer ecosystem. Bambu has publicly acknowledged that its slicer side is based on Slic3r, SuperSlicer, and PrusaSlicer, while its connection utility and cloud components remain proprietary.
That is exactly why the community is skeptical.
Bambu wants the benefits of open source when it helps Bambu enter the market, but when enthusiasts extend or restore functionality in ways Bambu dislikes, the company reaches for legal pressure and calls the result a threat to the ecosystem.

They cannot have it both ways
Open source is not “you may enhance this only when it preserves our commercial control.”
Open source has a share-and-share-alike culture. Bambu benefited from that culture when it suited them, then moved toward tighter control once the ecosystem became valuable.
The practical effect is that Bambu used legal pressure to bully an individual developer into taking down code, while also asking the community to trust Bambu’s private version of events.
That is not transparency.
That is intimidation wrapped in public-relations language.
If Bambu wants credibility, preserve real local ownership
If Bambu wants credibility, then make participation in the Bambu ecosystem free of cloud obligations.
Preserve fully functional local control for current products without forcing owners to choose between firmware updates and ownership rights. Publish clear, stable, documented local APIs. Stop using Bambu Connect as a gatekeeper. Stop treating third-party control as a tolerated exception instead of a normal ownership right.
Bambu can control its cloud. That is not the dispute.
The dispute is whether Bambu owners control their printers.
Right now, Bambu’s actions keep answering that question in the wrong direction.

Why the Clippy avatar?
The Clippy avatar is intentional.
Clippy started as Microsoft’s much-mocked Office assistant, but it has recently become a symbol in the consumer-rights and right-to-repair movement. The point is partly ironic: Clippy was annoying, but he was local, harmless, dismissible, and not trying to harvest your data, lock you into a cloud service, disable features after purchase, or turn your own device into a permission-based appliance.
In that sense, Clippy has become a shorthand protest against modern anti-owner product design. It is a small visual signal that says: I support user ownership, repairability, local control, and products that keep working without vendor permission.
