I fancy myself as someone who supports "the little guy", and the Dropbox team's story is an example of how "the big guys" totally and completely fell asleep in a pool of their own money while Dropbox built something that people wanted before other bigger players.
I therefore find it ironic that I don't support them with even just a little bit of money per month, when a big portion of the pitch for the job I currently work and the small project is "but we're different because we're smaller and therefore client focused!"
I hope everyone can reflect on who their money supports. But I'll tell you two large corporations I'm very happy to support: Bozzuto, my apartment company, and Bank of America, my bank.
I would never trust a small landlord to take care of me for the right price (I've been burned so many times by private owners). And well, I store my money in a place that is FDIC and regulated... Ok I have a credit union too :)
