I don't think enough people highlight how many startups depend on open source software to keep their costs low. Everyone knows it's the case, but it doesn't seem as highlighted when people talk about near-zero startup costs. Without Apache, PHP/Python/Ruby, MySQL, etc. etc. we'd all have to be buying webserver software, databases, frameworks, etc. or wasting a lot of time (and thus capital) rolling our own.
