What we'd need logically, the way steem is designed, is an incentive for witnesses to run IPFS nodes and pin files which hashes have been referenced on the chain. Just counting how much storage they are benefitting to the network would be enough to make me choose my witness votes :) But that's not going to happen :(

But yeah of course we understand your feelings, it's sadly just impossible for us to start pinning all the files indefinitely, it would just stack up and increase our maintenance and costs over time.

We've improved our storage strategy greatly in the last patch already, and I think tech evolves quickly and these issues will be overcome with time, in a natural way, with users holding copies of their files on their own devices (pc or phone).

Storage is getting cheaper and cheaper. Today it's easier than 1 year ago to run IPFS nodes without your bandwidth getting destroyed and starting pinning files. There's even some legit UIs where you don't need to be a hacker to use it. Also, usually the content creators need to keep copies of their source files (most youtubers do that), so why not keep them in IPFS directly and hit two birds with the same stone?
