This whole situation is toxic. She literally made a 1-line change in a configuration file with basically no downsides.

She also repeatedly re-opened and then merged the PR despite the other guy telling her to follow the format and wait for a review. Which she shouldn't have done. But then everyone started bashing her and .NET for other (similarly small) things and extrapolating that. Then there's this 1000 legalese word apology, and then people are bashing her for the apology.
