I've had good rapport with those who are honest about their startups being businesses, as they're usually also the same types who understand that working for them is just a job, and that a job at a startup comes with its own risks, as well.

People that go out of their way to say that their startups have a higher mission make me uneasy. I don't know if they're just trying to convince others that they're running something other than for-profit businesses driven by expected returns on investment for investors, or if they truly believe it themselves. It's either borderline manipulation or delusion, and neither are something I want to hitch myself to.
