I think that's pretty unfair. Wordpress didn't just magically "Become massively popular", it got so because it served many people's needs (there were plenty of alternative free/OSS blogging engines all along). Its developers put in thousands of hours' unpaid work before monetizing became an possibility. Providing supported/hosted services based on an open source solution, while continuing to release your work as open source, is about as noble as a business model can be, IMHO.
