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

Phones...uh, can be used as keyboards.
And remotes. And as a touchpad.
I use kde connect on my phone for my 3 10+ year old linux pcs that others would have thrown away. And to control 7 devices in total. Imagine trying to do that with a remote.
It's literally as simple as install app on phone and devices and pair.
Done.
You can get a good enough pc on amazon or walmart or a local garage sale for like 100$
You're just capitulating.
There is always another way.
