Is it reliable? Ad-blocking is a cat and mouse game and to actually have a useable ad-blocker it needs to be well maintained over a long period of time (for example like ublock origin).
Their concept looks nice, but they are researchers and I'm a bit afraid that they just drop that, write a paper about it and that's it. If there is no constant maintenance this will likely stop blocking YouTube Ads once Google deploys the next changes.
Update: checked the repo and it's actually a fork of ublock origin, so it should (for now) be pretty similar, but still they would have to keep maintaining that.
Wow didn't now that. I'm surprised I never heard of it, but I will definitely give it a try.
