A slightly structured reply, because apparently that is allowed now
Telling someone to “GTFO” because they gave constructive feedback is not exactly the high point of community discussion.
Yes, the P2S existed.
No, that does not automatically make the original post unreasonable.
The person did not say Bambu Lab committed a crime, stole their lunch money, or personally ruined 3D printing. They said they bought into the ecosystem, then saw a newer and more attractive model appear shortly after, and that it left a sour taste.
That is a perfectly normal customer reaction.
The actual point
The constructive part of the post was not:
“Bambu owes me everything.”
It was closer to:
“An upgrade path would improve customer loyalty.”
That is not an insane suggestion.
Companies do trade-ins, upgrade programs, loyalty discounts, accessory bundles, vouchers and goodwill offers all the time. Whether Bambu wants to do that is their decision, but pretending the suggestion itself is outrageous is a bit dramatic.
P1S vs P2S vs X2D
Buying a P1S when the P2S exists may weaken the argument a little.
It does not erase the point entirely.
The X2D is not just “another P2S”. It has a different feature set and a different appeal, especially for people looking at support material, dual-tool workflows or a more future-facing machine.
So yes, the buyer could have researched more.
Also yes, Bambu could benefit from clearer upgrade paths and better stock availability.
Both things can be true at the same time. Shocking, I know.
About the filament stock issue
The filament stock complaint is also completely fair.
A printer sitting idle because official filament is constantly out of stock is exactly the kind of thing that makes a new user question whether they bought into the right ecosystem.
That is useful feedback, not heresy.
TL;DR
“GTFO” is not an argument.
The P2S existing does not magically invalidate every customer frustration.
The original post was constructive, polite and made a reasonable loyalty/upgrade-path suggestion.
Disagreeing is fine.
Doing it with the social grace of a clogged nozzle is optional.
