There would also, presumably, be a fear of censorship targeting your entire company for over a subset of content. Back in 2018 Tumblr was blocked from Apple's app store [1] and responded by banning all adult content on the service [2] - and I'm sure there's a similar risk from school/workplace/ISP NSFW blocking services which are of course famous for over-reach.
Obviously, tumblr could have shifted everything NSFW to nsfwtumblr.com but for various reasons, a lot of sites seem to take a deniable 'turn-a-blind-eye' approach rather than visibly embracing NSFW content.

One thing I thought was interesting: Apple sells access to HBO & Cinemax through their TV app, but that access does not appear to include the adult content (or at least it does not display without an active subscription).
Or just kept using their web page?? I'm pretty sure that I can still access NSFW content in Safari.
I never understood what's the point of website-specific apps - like HN app or Reddit app or even Facebook & Twitter app - except of course some middle manager's quest for promotion.
Would you launch your new line of e-books on a site that is 95% porn and well known for porn?
No.
If you're a porn site, then you're pretty much going to be just that, it's its own content vertical, fairly distinguished from everything else.
Amazon is not known for porn. I didn't even know you could get porn there. Certainly, it's not 'online porn' which I would imagine would be the primary issue.
Tumblr became a place known for adult content so it was a problem. If Amazon started to do a lot of digital porn, like PornHub, it would be a problem.
If there is no 'search' on Patreon ... maybe they could keep it hidden. But it's a big risk.
