This represents an opportunity: these folks should just build their own apps which distribute content to their fans. Thats kind of what apps are for - the commoditisation of networks like Instagram and so on, is only really necessary because the technological barrier to entry is too high.

All it would take is for someone to open source a decent image browsing/payment transfer application, stick it on Github with a decent license that allows for re-use of the code, and 'services' like Instagram and Facebook will die the deserved death.

This is only a thing because the OS vendors are gate-keeping, and because they work hard to make it more and more difficult for people to write and distribute apps themselves...
