YouTube is currently experimenting with server-side ad injection. This means that the ad is being added directly into the video stream.
This breaks sponsorblock since now all timestamps are offset by the ad times.
For now, I set up the server to detect when someone is submitting from a browser with this happening and rejecting the submission to prevent the database from getting filled with incorrect submissions.
I can’t morally justify anything they are doing, and have been doing for many many years already. Yet I use their public services because they are unavailable. But I would never give money to such a company.
The fact that you use their services despite claiming to oppose them probably tells more about how you really feel than your words do. You’re benefiting from their abusive business model the same whey they themselves are. Justifying the continued use of their services by not paying is just a cope to deal with the cognitive dissonance.
