Some managers are fine screwing power users when they feel they are big enough. I will never buy a Chamberlain garage door opener for their similar stance against the Home Assistant community

I am sufficiently paranoid that I think this is drone part detection from the Chinese government.

Ya at this point I mainly know Bambu from their adversarial behavior. Some friends and I put three new printers online this past month and proudly none are Bambulabs.

Do they? They came to the realisation that they control a sufficient fraction of the market that your preference as a consumer no longer matters to them.

This feels like pressure from the state. I do not see why they would do this otherwise. If people use these printers at work, they may be willingly sending prototypes and designs to China. That would create a huge advantage, because the company could know who bought the printer, where they are located, and what they are working on. Since Chinese companies are required to comply with the government, corporate espionage seems like the most logical explanation to me.
