Yeah but the web has been this way since the mid 90's. It's been funded by ads the way that things that came before it were. Broadcast television is a good example. People switched to cable because of less ads and more channels with the expectation that there would be better content. That didn't last. Then we had tivo and DVRs and so many other products to get around ads. But the root of the problem is that people won't buy things they don't know about, won't use services they don't know about, will have a hard time looking for goods and services that they do want without some form of advertisement. Word of mouth is advertisment too when you get right down to it. The ads were often less intrusive but became more so over time because it's such a hotly contested area that pretty much every company small and large is throwing money at.

What's worthless garbage to some may be useful in a pinch to others. The point is that combating ads means taking away a source of revenue not just for ad aggregators and ad companies but for business full stop. I hate billboards. I'd be perfectly happy to never see a billboard again in my life. That being said, they have been effective ads for a long time, and have been used for good purposes occasionally (missing persons, unsolved crimes etc come to mind).

I'm not saying ads aren't more often than not intrusive, annoying, or lost on me. I actually do find them intrusive, run a pihole and a private DNS etc. But I also recognize that really laws to curtain what ads can do is a major problem, and that services have bills to pay.

And all that is to also say that worth is subjective.
