I'm just about sick of YouTube and YouTube TV not playing well with whatever device I've decided on. First it was YouTube and the Firestick, now it's YouTube TV and Roku. Frankly, how did Google end up with a good TV service? I'd rather not be relying on Google for TV streaming.
First, you can play YouTube without any problem on Firestick, they made the change 2 years ago. Second, you should give the new Chromecast device a try, it's far much better than Roku. Third, Google is asking Roku to support VP9, which is a much superior video coding format, I don't see any issue with this ask.
What's the point of singling them out?
