The problem isn't that Patreon took over everything, the problem is that everything is subject to the whims of payment processor censorship, and until that gets solved, there won't be ethical platforms that pop up; they won't be allowed to exist. In the meantime, we make do with what we have.
If Stripe (not that Stripe is ethical, but.. you know what I mean) - if Stripe got enough pressure that it got rid of its NSFW clause - I would drop everything at the earliest opportunity and immediately set up a system for direct credit card payments for supporters. The ecosystem would explode <3
It is genuinely possible for this space to be better, but it *can't* improve until the payment processors get sorted out.
