Why should we care if it’s financial failure for its owners as long as it brings the same value to its users?

If it's too much of a financial failure, it will shut down and provide zero value to its users.

Ironically enough, tumblr is going trough some sort of "indie/lo-fi" renaissance now that Automattic bought them. I don't think they even want to go back to being an alternative to FB/Instagram/Twitter.
