I watch YouTube on my TV. Using Firefox, with uBlock Origin. We have a laptop plugged into the TV, with a bluetooth keyboard. It is a vastly superior experience to any smart TV I have ever seen.
And also more than most people want to have setup in the living room. My wife would rather have ads on YouTube occasionally than an ugly computer plugged in all the time. It’s also more difficult to deal with than a remote you can work one handed.
If I were their investor I would not be happy.
