But I think the invocation of imgur brings up a good point. Was what we believed imgur to be ever actually economically viable? They were "bootstrapped" but $40 million in 2013, back before almost all of their impact.

At least some of the funded things that 'sell out' were just never viable to begin with.

It's far from clear to me that reddit couldn't have become more like Wikipedia-- driven by its community and funded through public support-- but there are lots of things that we could decry for violating their purpose that I think couldn't exist economically in their original more public-spirited form.

I find myself wondering more how often alternatives that are viable but just a little less good are driven out of the market or prevented from ever being created by funded alternatives which aren't viable... leaving us stuck on a bait and switch tread-mill while the services we actually need die for lack of support.
