Remember tech-companies exist to make money, not to "do good." Whatever problem they are supposedly working on, they are only doing it because someone thinks they can eventually turn it into a revenue stream. Don't drink the kool-aid, be a mercenary and get as much out of it that you can until you can leave for good. Dont' be the like the smuck's that are still working at twitter.
Yup, and this applies to any company. If you don't own the business, you are a line item, not "family". Always be ready to jump ship for a better opportunity, because they will do the same.
