Fuck you patterns are everywhere on the web nowaday.
Some of the most annoying to me:
Twitch trying to discourage the use of the embedded player/non official players (like VLC) by replacing the content by a fullscreen purple picture asking you to watch on twitch.tv.
Reddit trying to force mobile user to use the reddit app as soon as the content is marked NSFW.
Instagram forcing me to login to view pictures.
Twitter asking me to see who someone is following.
