The fact that somebody made a Chrome extension that doesn't work as well as a Firefox one is no indication of some grand conspiracy. It's also no indication that they're going to be removing AdBlock from their site. Once again, it's based on assumptions.
The fact is FVD used to work with youtube. Then it was banned from Chrome store. After that they republished the extension but without youtube support.
That is the fact.
Now for other things, only time will tell.
