If somebody proposed to build you a house with slave labor free of charge, would you be happy about it?

Since the answer is quite obvious, we can clearly state that even if something is free and beneficial for you, there is a line which you shouldn't cross.

That out of the way, we now have to figure out where to draw this line. It just so happens that for a lot of people using a technology that actively destroys our environment, makes every computiational device more expensive, literally makes it's users dumber, and is built with very ethically questionable methods lies beyond the line.

Oh, if that's not enough, LLMs can kill you if you are psychologically unstable.
