NLCH's idea is right, however, it's tad more complex than "you give a company the right to dictate what you can or can not consume".
Raw biology and common sense dictate that social superstructures have to care about members of said structures (citizens) propagating successfully. Said social superstructures' populations will dwindle otherwise, and superstructures themselves would gonna disappear as a result.
Inappropriate porn (guro, pedo, bestiality, whatever glorifies unhealthy sexual intercourse) affects these matters directly.
Payment gateway providers, for some reason, got sick of this bullshit and pulled the plug so hard so even Steam (with all their indifference) was shaken a little. Despite them [payment providers] not giving a damn about anything but profits. Something bigger scared them, apparently. Which is weird to see - however, it's only about 1/2 of the real problem. And it - believe me or not - is a lesser half.
Now, this probably will gonna have me permabanned here too, however, I'll take a liberty to tell about second half of the problem without self-censoring things too much. I'll damn explode otherwise. This thought is pestering me since one of Patreon purges of 2018, time to spill it a little.
The second half of the problem is that you can't just ban things blindly.
You have to provide alternatives.
Reasonable, sensible alternatives.
Example from our grim past: various sexual deviations were banned in Germany in late-to-middle of past century.
HOWEVER
An alternative was offered. As a matter of fact, more than one, unified by a singular relatively sane idea.
A culture of appreciation of healthy human body. And an encouragement to give birth to healthy children.
Do note that I refer to this specific point of space-time as an example of a right IDEA about "how and why should we deal with porn". Not as an example of right EXECUTION of said idea (since it's obvious that the execution was shite and the world would be a bit better place if all that shite wouldn't happen).
Yes, current carpet-bans of payments to prawn creators puts the author(s) of this idea well below German politicians of 193x. Simply because payment ban initiators didn't offered any sane alternative AT ALL.
> Then it's LGBT content, because it's almost sexual anyways.
Please stop dragging LGBTQ+ into this.
Structures which support this stuff officially deserved this specific predicament by doing everything to make healthy relationships between heterosexual people viewed as a deviation.
I'll probably change my mind once I won't have to guess the gender of displayed person in whatever new porn piece of "art" ended up on my desktop. I have to guess too damn often nowadays.
