As recent events have clearly demonstrated, FOSS is by no means immune to security holes. Is paid, closed-source software less secure? On one hand, it does lack community oversight of the code base. (Although clearly with a sufficiently complex code base, backdoors can exist for years without anyone noticing anyway, and it could be argued that intentional back doors would be more easily installed in open source projects.) On the other hand though, paid software is operated by a team whose job it is to keep the service secure. All that aside though, I certainly can't see any logical argument for the statement "Free software is a prerequisite for digital security." It could be argued that open source software is such a prerequisite (although I wouldn't necessarily agree), but if anything I expect that paying for software would ultimately tend to make it more secure.
