I tried one of their legit movies once. It was super blurry and interrupted every 10 minutes by ads. It was ridiculous. I got the impression it exists as a scapegoat only.
Tumblr definitely had (has?) cornered niche blogging too though I think? Especially photo-heavy content, as a Wordpress alternative for a personal blog not a 'website'? I think anyway, honestly didn't realise it was significantly used for porn.
OnlyFans on the other hand... didn't they recently say something (trying to appease payment provider I think) about being a general purpose fan payment/follower thing (like Patreon) not just porn? Sure.. it just so happens that the latter category 'rounds to 100' as you say, but yes, general purpose and theory and even intent perhaps!
Oh that's undoubtedly a lot, of course. If Plex somehow prevented (built-in CV detection of anything commercial vs. home video being played from your own library, say) pirated content I think MAU would drop approximately 100% though!
Ripping a DVD collection to which I own the originals is not piracy in my country.
In fact, we pay a tax by the GB for every writable storage medium we purchase (everything, from HDDs to the SD card I load into my camera, including actual phones) that goes to authors and accounts for “private copies” like those.
I use Plex and the RAWs from my camera take a lot more of my media server's HDD than any DVD rips.
I sympathise and think that should be legal in any country (I've long thought that the sale should be of 'the right to view' more than the physical medium, Sony and others toyed with it for BluRay which I was thrilled aboutthe potential future of, but canned it recently-ish) but I don't think that materially affects my hypothetical, for one thing it could trivially be applied only to other regions.
Serious question: do you think the majority of people aren't getting themselves off (or working their way to getting themselves off in short order) when consuming nudes, erotica and nsfw? The follow up question would then be if the majority of people are using the art to get themselves off is said art not then porn?
"these pirates, who constitute a percentage of our business that rounds to 100, are really getting in the way of our business"
