STFU about linux support in mainstream titles. It's just not going to happen no matter how much you wish it.
Now that CryEngine, Source, and Unity are all on Linux, it just might happen. Anything that lowers the barrier to entry for the developers is a good thing, and increases the possibility for AAA games on Linux. We already have one AAA title on Linux, Metro Last Light.
I hate let's play guys, they are all hyperactive frustrated kids.
Certainly not all. I could give you a big list of them that aren't. Sure Pewdie and Toby are hyperactive (though they're both old enough to not be called kids), but there are many others that are not.
It's already happened: want to upload Youtube videos? You have to subscribe to Google+ and its invasive TOS. Don't want G+? You have to use Vimeo or Dailymotion or other inferior online video services. And because Google has grown so massive, they have the means to drive Vimeo and Dailymotion out of business for good.
Vimeo isn't inferior, it just has a smaller userbase. It could be argued it has a different purpose as well, as there are certain kinds of videos (video game let's plays, for instance) that they don't allow on their service. Also, if the service is inferior, maybe they should improve their product, making it easier for them to compete with YouTube.
Then I suggest you get an MRI
That's just like, your opinion, man.
