This isn't true – the only billing system bug I've seen undercharged. Also if it was an overcharge, they would have made customer whole, whereas they wrote off the undercharge.

Microsoft doesn't really gain anything here – there's a clear "forked from" qualifier in the repo, they aren't republishing these packages, etc. The only people who noticed noticed in a negative light.

To reiterate, I'm not saying there's malicious intent in any single bug. Yes, billing errors don't lead to more revenue for the firm. I'm describing rather a systemic bias in incentives for the people doing the work (programmers) and supervising the work (managers).
