Ah. Yes, I suppose. As it is easier to find exploits in service of closing them as well as in using them (security researchers seem to mostly come down on the side that this averages out as more secure). If that's what you meant, I apologise for the misinterpretation. This particular article doesn't make that point, though, so I remain with the feeling that mentioning the license model in the title is irrelevant and a bit misleading.
