I have no problems with people putting ads on their videos. They can't control what software I use on my computer though. If they want to put ads on their videos, that's none of my business. And if I choose to use adblock, that's none of their business.
Regarding other issues, YouTube does indeed suck. HD is unusable - I can get HD Netflix, HD Vimeo, HD Dailymotion, and so on, but YouTube's HD just doesn't work because their servers are so slow. Their copyright policy is the worst of all video sharing sites. The interface sucks and there are a lot of videos that are "not available on mobile."
hmm, i have probs with youtube but none of these really.
my prob is that youtube always chooses the lowest quality video. it's annoying. not for slowness or anything like that (i don't find it slow), it's just the changing the res manually is annoying when you have a playlist of 30 vids to wade through.
why the holy hell does it not default to the highest res available ffs!? there are options in your account but only when you go to fullscreen.
then, when you watch a video in fullscreen you have that stupidly large "press escape to exit fullscreen" message that last way too long. once that's gone - then i can start playing the video.
oooh, wait, that's not the end. now there's a huge bar at the top and a seekbar at the bottom. they appear anytime i move the mouse. why no option to not show these unless the mouse moves to the top or bottom of the screen? i mean even homer simpson mashing buttons on his keyboard would get out of a video eventually ffs!
any video over 2 mins or so i just download now and watch in media player classic HC. it's actually less hassle than battling youtube at times
