Don't be silly. If you can't look at it without paying, it isn't open source.

Everyone always says this, but the majority of the community is very much against you making money on it and will destroy any chances if you making any sort of profit by releasing the source for free (which is allowed under the license).

Most people can't compile software. Forking and releasing a compiled free version would be more likely to kill a project.

But then see also Pysol; a free open source program that was being sold by sneaky companies. The devs decided to stop releasing it.
