YouTube's ad problem just got worse: Users now seeing 90-second unskippable ads!

This is a most excellent place for technology news and articles.
If the ads starts running too long I just hit the back button or close the window and go look for something else to watch.
I used that trick 10 years ago when ads were optional or 5-10 seconds long. After they crossed the line with forced ads i blocked them and never looked back.
