Even on sites like that you can’t get everything, since it depends on subscribers actually sharing accounts and not all creators will have those. Trust me, I’ve really scoured the internet for certain creators’ content and it’s just not out there.
Also there are sites beyond OF, a lot actually. There’s just no way to get everything you want easily if you’re into certain stuff/creators.
I get that you find no value in porn regardless of type so you wouldn’t pay for it, which is fine, the majority of people don’t see the need to pay for porn either, but I hope you’ll at least understand some people do find value in the content they like, enough to support it. It’s like subscribing to a youtuber’s patreon, their content is still free for everyone but some still want to financially help them.
From a regular user standpoint pretty much all modern browsers throw up warnings and block the page from initially loading if it’s not https, which discourages people from viewing it.
