I pay for youtube because I watch quite a lot of stuff on it and much of the content I think is way higher quality than anything on "TV". I'm happy to pay to get rid of the adverts and happy for the creators to get some cash.
However ... I'm now getting quite fed up with the lengthy sponsor segments that appear in many videos. I've paid to not waste my time watching adverts; now they are being added in on the sly. That's not what the deal was.
