Well, they are guesses at least. I think I pointed that out earlier. You, and I and everyone else here do not have enough data to know what’s going on, how many are affected, etc.
I’m not belittling you at all, but I have to disagree that anyone here is “making an educated guess” no matter how much we know about printers.
I don’t think a reasonable person would think that Bambu is doing some sort of coverup, nor do I think they ordered thousands of beds that they knew would be defective. I don’t think you do either.
Having been involved in this issue right from when it started being reported I can tell you that the number I’ve seen is actually fairly small overall, but the noise level is high because people are outraged.
