I lack the money to buy something from every creator I watch (literally over 100 channels subbed to), and premium genuinely does pay them more than ads. Sure, like half is going to google, but it's definitely the easier way to support the creators that does actually pay them.
Yes, but if I was only doing it for no ads, I'd rather just use ad block. Instead, I'm doing to to support the creators I watch in the laziest way possible, because I'm letting Google do all the work to spread the money out.
