The crux of the question is "how people find internet resources". And the answer is that, generally, ad-driven companies have no interest in showing their users this kind of stuff, and have taken over pretty much every entrypoint.
For instance, if I was to build a webgame, there is zero chance it could be found through Google nowadays. If I made an app, I would have to plead with Google's or Apple's store.
I could share it on e.g. Reddit, Twitter or FB, but that would be a tiny trickle of users, and the odds of them staying on my platform and its associated forums would be extrelemy low, because the users aren't actually looking for it when they see it.
Also it wouldn't be large enough to be their daily doomscrolling experience (and there is zero chance it could be integrated to it using e.g. RSS feeds). On top of that, any site not algorithmically optimizing content shown for maximum addiction would not capture users in the long run.
Guess what option I have left to show my thing to people? Pay the ad-tech business. That's not something easy for an association or an individual who aren't looking to create revenue streams.
Okay, so what's your solution? People don't use search engines because they have ads; they use them for another reason. Can you compete with that reason?
You can still make these. Why do people choose platforms with ads on over these things you remember, do you think?
