Tubular is a clone of Newpipe by the way, newpipe's devs didn't want to allow the sponsorblock plugin so it had to be forked.
Well or not show the sponsors to premium users. They could simply upload a separate premium version. Don't forget, these content creators are already getting a lot more money from YT when a premium user views their vids. So they're not entitled.
They can walk away but where would they go?? Besides, more and more people are using sponsorblock since it's become totally insane with these.
And no I don't tend to watch many with sponsor crap in them because they aren't actually very good (think the low-quality crap from LTT etc). The best channels (EEVBlog is one notable one) don't have sponsors at all because they're made for love.
What I am not doing is watching the sponsorship segments anyway. So yeah I use sponsorblock. And I use Ublock origin or revanced to remove the ads too because there's way too many now.
It's just that as it stands it makes no sense to do so. I still get ads so there's nothing in it for me. And if I use sponsorblock I might as well go the full way.
It's really on YouTube that they have let this situation be created. They should have stopped sponsor segments the moment they arrived.
Fix that and then I'll pay.
Until then I just block the ads and the sponsors.
