Here is the thing you have to understand about VCs (and therefore, companies and websites that have accepted VC money), always and forever. Repeat it like a mantra.

--- Venture capitalists do not invest in the company. Venture capitalists invest in the exit. ---

Eventually any site, app whatever has a Sell Out Moment. They get bought by a big established corp, they go IPO, something. There is an "Exit". If you accept VC money, you are *promising* that Exit day is coming and it will be *big*.

@mcc excellent point.
This all lays bare the point that for any company to exist, it or its founders most regularly demonstrate commitment to the ideal of extracting wealth from those poorer than them, and giving almost all of it to those richer than them.
Rent, mortgage, small business loan, rounds of investment, and even VC money - they're all coded terms for wealth extraction and upwards wealth transfer. They differ in terms of the amounts transferred and the risk involved, but they all achieve the same underlying purpose: if you're not complicit in this uber-pyramid scheme, you don't get to have a business. Or a home
