@dansup Personally, I don't care about things being for-profit. Hell, I'm a for-profit enterprise!

I do think that overwhelming scale and the potential for monopolies matter, and I hope that doesn't happen (I don't think it will, Tumblr's too weird).

The Fediverse is currently too small. Even small-time creators are going to find it hard to find an audience big enough to sustain them. Gaining access to Tumblr's users is really quick win in this regard.
