I strongly recommend people study history, and understand human nature at both scientific and societal levels. There is too much to discuss here, but in brief:
Homo-sapiens, much like other primates, create status hierarchies while competing for resources and mates. Status is directly proportional to the ability to exercise power. All of human history has been a result of this inter and intra-hierachy competition.
In a police state such as the modern US, the lowest police officer has an unimaginably higher potential to exercise power than any median income citizen. As such, that power is often exercised. As the author realized, you have no ability to fight back in a police state. You can sue, but good luck getting results.
So the real question is, why do you think your startup is worth pursuing given the situation you're in? Do you really think "bringing transparency to the food industry", or the thousands of other startups that go through YC, are even relevant given the reality of the US police state?
This has been my biggest criticism of "Hacker" culture. Closing your eyes and pretending you live in Galt's Gluch is not going to make it a reality. Wake up and look at the world around you and realize that just because you haven't been crushed by the state yet, doesn't mean it's never going to happen. Once you realize that, your priorities will hopefully shift in a more reasonable direction.
Nobody, and I mean nobody, is safe from totalitarian police states. This is a fact history has shown repeatedly.
Act accordingly.
P.S. Just saw that immediately race was brought up. As a tip to anyone who wants to make a difference, people in power will divide you into as many groups as you let them in order to subjugate you. When the system is in place, it doesn't matter what ethnicity you belong to. If you piss off the wrong person, you're finished. The trick is to unify to disassemble the monstrosity, not balkanize into smaller and ever more powerless units based on: race, income, sex, height, attractiveness, beliefs, democrat/republican, pro-life/pro-choice, LBGT-hetero, pro-KONY/anti-KONY, ...
Please, understand power. Understand how little you have, and how to make best use of it to attain your goals. Balkanize at your own peril.
