Some combination of posting to ipfs then linking with the cloudflare ipfs gateway… not sure how smooth that workflow is.

Hosting cost money. Even if there is a free and open source hosting solution it’s going to cost money to run. Without venture capital money or advertisements or some monetization scheme, you can’t host it for free. Wikipedia works because they beg for donations.

IPFS works because there’s some weird cryptologic money funnel going on in the background. Probably won’t last forever.
