Previously, we were limited in how we could apply our 3rd-Party Tracker Loading Protection on Microsoft tracking scripts due to a policy requirement related to our use of Bing as a source for our private search results
I couldn't remember the details exactly, but basically up until then they were allowing Microsoft tracking despite all their advertising claiming they wouldn't track users.
I feel like Microsoft is way more shameless about their shady stuff. They've been messing around with impersonating google/chrome for awhile now, they recently had that thing where they would copy all your open chrome tabs, and then when you started your computer it would open edge with all your chrome tabs to trick people into using edge instead.
