Ehh... I would wager on Roku being more dug-in here. For them, control over their hardware is an existential concern. For Google, streaming television is one of their many dalliances that may or not still be active 5 years from now.

Every television that I've bought over the past 5-10 years has Roku built into it. I know that some people prefer to plug in Amazon devices instead, and that's perfectly fine (not that Amazon is any "less evil" of a company than Google or Roku). But I use Roku's platform because it's usually the hardware default, and I like the UI well enough.

I'm already pissed that Google has raised their prices to the point where I no longer save any money compared to what I used to pay for cable+internet. And then dropped sports coverage for my local baseball team anyway. If YouTube TV disappears from Roku's platform, then I'll just sign up for Hulu or whatever 5 minutes later. Or fuck it, I might just go back to cable. These over-the-top, "skinny bundles" have been a bait and switch in practice.
