I think Id have to say youtube. That shitty site just keeps getting shittier and just when you think they cant fuck things up more than they have they set new standards of shitty shitfullness.
There was once a day long ago when the next video in que was remotely relevant to your query or previously played video. Now you could be watching a documentary and two videos later they are shoveling some completely irrelevant shit at you.
Then they started vpn blocking. 95℅ of the time I cant even play a video. Or it plays for a minute then errors out with "something went wrong".
For years yt-dlp saved my ass when I needed a video. Now works about 10% of the time.
