> Why on earth would they not use their own platform to present their content?

I know one of them personally, and I think in her case, she may have had a few hundred people following her art blog, while on Instagram, she quickly amassed over 100,000 followers, so when she stopped updating the blog, she lost less than 1% of her fans.

It comes down to people knowing how to follow Instagram/Facebook accounts, while they haven't even heard of RSS.

Of course I can imagine that Instagram, Facebook and Co. are more popular and accessible to her audience.

Again, I'm not recommending giving up those channels, but betting your content on a platform that will be gone/unpopular at some point (they all come and go) while abandoning the constant, central presence of your very own website, regardless of how small the following may be, seems short sighted. This has nothing to do with RSS.
