It was different, but it was great. I would absolutely go back.
But if I had to choose one or the other, I'd choose no ads.
And that's only comparing "then" to "now". I'm confident that "now" will get worse in the future, making "then" all the more appealing!
I'm all for the idea of small content creators being able to afford to create their work. I wish content creation did not attract so many people who only do it for money, though. Maybe this would be achievable if the rewards were lower. Advertising sucks all the air out of the room for alternative funding mechanisms. If ads were eliminated, there would be other mechanisms.
However, back in reality, I'll concede that (e.g.) Google's massive ad revenue has given them the ability to try a thousand other things, a handful of which will be long-term valuable to the world. But the cost is immense.
I loved Usenet, but I also appreciated being able to have a personal webpage for free as a kid, and that was ad-supported.
There were free ways to get on the net, and to host web pages, before 1995. And for many years after that, you could pay for ISP access, which would come with the ability to host pages.
We're still paying for ISP access, we just get fewer services with it. That could change.
