It's maddening that quite a few people are jumping to defend Bambu here.

Principally if you sell a device with a certain functionality and you later modify that device later to remove that functionality that is called theft. It does not matter the slightest bit whether you break into someone's house to physically alter the device or whether you remotely install a malicious software update to do that.

But what's even more insane here is that some people are claiming that BambooLabs would somehow have the right to do this, because while BambooLab might not have the right to limit the hardware they already sold (which they did and these people just pretend did not happen) they have the right to limit their printer client software under the license conditions they impose on it from the beginning, when their printer client is literally a modification of AGPL licensed software. The entire point of the GPL is to prevent people like BambooLabs from doing exactly this. The AGPL is literally the single license with the most restrictions on BambooLabs to ensure that the users of the software — the customers — do not have any restrictions in what they can do with it.

Some people are seeing this situation and just decide to side with the company against their customers on imposing restrictions on an already sold product after the sale and they are literally making shit up to justify it.

Edit: For people who do not know what this is about: Someone modified AGPL software to reenable features of these 3D printers that BambooLabs stole after the sale and BambooLabs sent a legal threat to them to stop distributing the software.
