Maybe also related: a lot of startups take VC funding and current VC funding has shady origins. Some funds are powered by illegal russian investment money hidden through one or two layers of LPs, some is money of different questionable provenance, and some is actually clean money from sources you would expect. but, free money, so who cares if your startup is built on peasant blood money?
Once you've taken VC funding, you're not just in startups anymore, you're in politics of money. Money politics are the worst kind — it blinds you to anything illegal or immoral as long as the money keeps flowing.
Indiscriminate down votes have to be met with indiscriminate up votes. What a daft situation.
Edit: Ah! That also explains why explanatory comments aren't required for down votes - preferential control. I didn't realise how rigged this is.
(I doubt it's Evan Spiegel himself. It would be hilarious if it were so. I'd guess that it's a Snapchat employee of relatively low significance, but I really have no idea who it is.)
