Legacy TV is dying out anyway, so eventually, some manufacturers would start making TVs without HEVC that would be targeted for Internet video and it will only snowball.
Sure. So called "cord cutting" trend has been around for a while already, and legacy TV has been losing users in millions.

TL;DR: legacy TV is dead already, it just doesn't know it yet (or rather they already know it, but want to squeeze as much money as they can, before they hit the dust).
When it does come to pay TV, note that pay TV is still growing in Western Europe, mostly in places where they've historically had very little marketshare (v. terrestrial broadcasting).
