I saw your blog post, it's a song right? Yeah that's normal, nothing new. Most of the time it's they get to monetize it and it doesn't get blocked, but sometimes it does get blocked, depends on the companies and it's their decision sadly. You're kinda lucky since it only blocked it in two countries.
I uploaded an Avengers Endgame clip to YouTube recently and Disney blocked the video immediately in all countries. It's automatic, and even if you dispute it, you have little chances of winning.
