I agree, but for more people than one might imagine is my reasoning.
A group of 5-10 friends and/or family members can for example together pay $8/month for managed hosting. No technical skills needed. Still not for everyone but a viable route for some.
On the other hand, the Twitter instance doesn't let us carry over anything to another platform and we were okay with that ;)
I was just made aware that @mastohost is pausing signups as many are going this route...
