> In-house development

... keeps resulting in shit code, too! There's no evidence standards of quality are rising. In my own extremely limited view of in-house software -- i.e. my own professional experience -- code quality is crap, standard quality practices are very low and actually worse than in FOSS projects (I've seen someone mention more than once that "this crap PR simply wouldn't fly if this were an open source project, it's so bad nobody would want to review it!"), absolutely dumb bugs keep hitting production, and people think of automated testing as "that thing we don't want to do".

In-house code is just code you don't know is garbage because you cannot look at the code.
