$100/year is less than $9/month. You’re not going to get very many rentals with that. Whereas Usenet, you can get as much as you want. $9 a month is also less or the same as a single subscription to a streaming service. I’d gladly pay $9 for one place to have everything I want. I’ve never used usenet, just pointing out why it would be worth to some people to pay for it.
