Just those 4 projects represented 18% of the total scanned OSS code. 
Those 4 alone could skew the results in favor of OSS.

By definition it's hobbyware, since most of it is created by unpaid 
developers in their spare time, for fun.

And it shows in the usage, where you get ridiculous bugs such as mice 
being identified as keyboards, same app listed 16x, apps not sorted 
alphabetically, Trash file handling inconsistencies, inability to sort 
numbers (KDiskFree), etc.

The most bullshit bugs I've ever seen have been in open source.

Coverity's code is closed source.  So is yours.  And Creepy's.  And 
SMelzzzzz's. And every developer's here on cola.

I downloaded
http://softwareintegrity.coverity.com/rs/coverity/images/2013-Coverity-Scan-Report.pdf

Look at Table 4: it's horseshit.  Their supposed "Average Defect 
Density" increased 300%+ from 2009 to 2010, then suddenly dropped by 44% 
in 2011.

Ridiculous.
