Roku and TCL are being sued for allegedly bricking smart TVs with bad updates

That's cool that you're using it as a nas, and I'm glad it's working out for you
Myself, I want something easily controllable from a remote, so that when I come back from work I can just relax without seeing a keyboard and having to work with a pc.
I tried Librelec and lineageOS TV into a mini pc, but they all had various quirks, so I'm sticking to my TCL for now.
