I worked at engineers-call-the-shots fintech and later SV shops for many years. No, their in-house code is not worse than open-source.

In fact one can safely say that top companies that attract top talent also have methodologies in place that lead to better than average code quality.

If you are comparing the top engineering shops to open source, you should also pick the top (quality) open source projects. Apples to apples.

Most in-house code is crap.
