I started Smithereen in autumn of 2019. Bluesky started around first half of 2020. After all this time, and considering my extreme laziness, I have something resembling an actual product. It works, I'm writing this comment from it. What do they have after 2+ years? A bunch of promises and nothing material.
If you don't know ipfs allows to share files in decentralized manner but it sucks. Even if the origin is online, you may have random errors trying to fetch files from it.
In fact ipfs without web gateways is absolutely impossible to use.
