Yes, that is adding controls and using a database from the SponsorBlock server.
What I mean is a plugin cannot see the video. Like you can't write
if(screen == adScreen) {
then skipToNextSegment();
}
The plugin isn't reading the video, it is getting info from a database. For AI or machine learning to work ad injection, which might change for every user, doing what SponsorBlock is doing is not enough.
