Immutability is not real. There is always a hosting with files. For this reason a community should manage such uploads, and not a random community without rules or values, and not onto a nameless server, for things to be reasonably flexible at first.

Permanence comes from distributivity and from real hardware, not from IPFS. Its pinning is only a few days long, in reality. It's not really a hosting, rather a sporadic buffer.
