A comment on VC-funded companies with products in the fediverse:
My company, StatusNet, ran identi.ca for a long time on VC funding.
It's hard to get a 10x return in markets where open standards prevail. But it's fine to try.
There are other ways to fund services in the fediverse. https://cosocial.ca/ is a cooperative, for example.
If the fediverse remains diverse and competitive, and community, coop and family servers have a place, I'm not opposed to VC-backed companies participating.
Also, I totally think @timbray makes good points. We're pretty close on this, but not quite in agreement. Which is OK!
