Still takes too long to boot to display.

TVs long ago used to take up to 10 seconds to startup because the electron gun at the back of the CRT needed time to heat up. The advent of TFT panels gave us the hope that that wait would be a thing of the past. Now instead we wait minutes for its spyware, adware and bloatware ridden OS to boot up and phone home. We're living is a world that's the opposite of what technology promised us.

For now.

wait until a technology like sidewalk(or heck, IOT-scale 5g with sim-less connection to data-herding servers)

Unless it refuses to turn on without the internet connection.

What TV doesn't start without an internet connection?

TV has no purpose connecting to internet in the first place. But that's the reality now. It's more or less guaranteed that this slippery slope will lead to TVs that won't start without an internet connection - and only such TVs soon afterwards.

Just wait. With time this will happen, sooner than later I'm sure.
