They profit from this work, but like the grasshopper
in the famous fable, they aren't willing to participate in the investment that made the profit possible. Too bad, because if they did -- I think their companies would be stronger as a result.

Had we had a longer easier runway for Radio and Manila, Tumblr might have gone further on less investment.
