I wonder why that is.
> This isn't always intentional, even.
I don't think everyone at Google is evil. There are many passionate engineers and hackers like you and me. However, if a Youtube developer has an issue with something running extraordinarily slowly, it's a much shorter call to the Chrome department than it would be to Apple's Safari or Mozilla's Firefox. So while developers might not be actively hindering other browsers, they are developing for Chrome. That it technically works on other browsers is a requirement but optimizing for the competition's browsers is not something I imagine management allocates hours for.
The end result is that they are hindering competition in the browser market, and quite a few people saw that coming. Still, even more people (vastly more people) either did not care or know and recommended Chrome anyway.
> Nobody is complaining their Android or iOS phone has DRM, do they?
My Android phone does not have DRM beyond what it in the SIM and I am complaining about people whose phones do. Many friends and peers share my view on this, so it's at least not "nobody".
