I'm not as sure about that; products like Wordpress have an amplification effect with their users. The average person who uses Wordpress doesn't just have one Wordpress site; they have dozens to thousands, because they're actually an agency/contracting firm/whatever. Its the same, but opposite, reason why Microsoft can build products that piss off literally every corporate end-user they've got on the whole planet; they aren't selling to corporate end-users, they're selling to people with higher leverage, and they haven't pissed those people off.
