Very personally, I see it as contributing a small amount of a very non-scarce resource (bandwidth, disk space, computing power) so that I have greater control over the platform I'm using. I loved both Twitter and Medium, but the corporations that run them have different ideas about what they're for. I see web decentralised about letting the user choose their experience instead of having it enforced on them.
