If Web3 becomes popular, it frees the online tip jar from a particular platform (eg Patreon) and decentralizes it so anyone can set it up for themselves, with far lower network effects required.
But... advertising isn't why these services trend towards angering content. Engagement is why. Whether you are paying with ad views or micropayments, if services want you to keep engaged then they will be incentivized to promote this kind of content. And since things like youtube premium (or whatever it is currently called) exist today and per-view payment systems have been set up by Google in the past (and already died), I don't think that funding these websites with BTC donations or whatever would change a thing.
If you think the firehose of self-referential click-bait needs to be made even more addictive, I'm really not sure what Web3 can offer.
OTOH, reintroducing the friction of having to decide whether the next click is worth your time and attention (i.e. money) is where it's at.
The proposed web3 model seems far more likely to be like those abusive micro-payment games with constant prompts to pay for something, with a page's worth of content moved behind successive paywalls since publishers aren't going to switch to a system which pays even less and you'd need to ask permission before charging someone.
This also adds problems with people who don't have money or aren't allowed to spend it (children, elderly, etc.) or the same scandals when those people are taken advantage of, not to mention the privacy impacts of effectively creating a super-cookie which can be used to track people all over the web.
