Microsoft reveals all the Google things it removed in its Chromium Edge browser

As I understand it, the bulk of the work on Chromium is currently being done by google developers and not so strangely, Chromium has a bunch of google services hardwired in to it. Take a look at the list of services Microsoft says that they have replaced or turned of in the linked article.
Having developers that don't have share that google-centric world view working on chromium may give us a more neutral browser.
If we end up with a hard fork, having a major player like Microsoft in the mix may dilute google's total dominance of the browser by giving us a compatible browser that does not feed your data into google.
Either way, time to bring out the pop corn.
Also note the paper is largely overblown and possibly just plain wrong https://love2dev.com/pwa/marionet-attack/
