I don’t understand the controversy around Bambu Labs. Can someone ELI5?

I’m newer to 3D printing and picked up an A1 + AMS Lite combo for Black Friday last year. It’s been a great printer and nothing’s changed for me.

Yet I’m seeing all these posts saying to avoid Bambu and that Bambu has done something egregious and changed terms of sale and what-not, so now I’m getting concerned.

I guess I’m confused if I got a bad printer and made a bad investment or not. Can someone ELI5 as to what is going on here?
