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

...ok I've never felt more justified in completely turning off my TCL's ability to connect to the internet, then.
damn. the only reason I initially did it was because they'd introduced an update that put ads on the bottom of the screen every hour or so.
factory reset, internet gone. dumb TV is the best TV.
