I mean, I have a conspiracy theory that the new Edge was a coup to destroy Microsoft's web platform from within by "former" Google employees hired by Microsoft that I could spin you.
But Alex is just very much promoting the concept that Chromium be the sole standard implementation for the web.
You dont seem to understand how corruption works. Quid pro quo is hilariously easy to avoid doing. If he’s been told to do this by google, then in 5 years he will be back at google with a big fat signing bonus as compensation for sabotaging Microsoft. This seems unlikely tho. He just likes google and promotes it because he is “bought in”.
He did used to be at Google, until 2021.
