Basically, the only way is to disconnect the TV and use it as a dumb screen. Lineageos supports a few set top boxes (see here).

I heard (take it as hearsay) that some smart TV periodically capture screenshots of what’s on screen and upload it, so it actually disconnecting the tv from the network could (again, hearsay) make a real difference.

It’s no secret that we trade our information for access to the Internet.

I pay a monthly subscription for access to the Internet (actually two: one for the landline and one for my phone).

So what do you prefer a subscription based Internet with privacy protection or a free internet with companies allowed to take and sell your data

Either one would be better than what we have now, which is not free and not private.

What’s crashing? the Linux host? Virtualbox? the windows guest?
