I also heard that. But is it actually the case that a significant number of people don’t use the file explorer (because they often use tablets/smartphones and not a desktop/laptop PC as main device, which is what I heard as reason) or is it just something people say?
I am a tech nerd over 30, using a mixture of windows and linux, and watch porn. While I’m not a furry, they have great art IMHO so people can share it even if they aren’t 100% into it. Some of it might even be ideologically driven, against the anti-porn drive: Add a lot of good porn content so that in case e.g. Reddit shuts down NSFW there is a good alternative.
