Why would Chrome being run a foundation that is funded overwhelmingly by Alphabet make a difference? Chromium is already public -- aren't there already forks that focus on privacy and ad blocking?
The same reason every conflict of interest is a problem. You're not advocating for what's best for the side you are supposed to be representing because you are also representing a self interest.
This is absolutely not about quality but a political move to counteract ad blocking extensions and companies. While the intent seems noble, it's likely to cause no real improvements compared to better existing options like not serving these formats at all.
