I have to use Edge on one of the work computers, and after a recent update it changed my search engine from startpage.com to bing, and informed me with a small pop-up by the search bar that they were changing my search engine for my protection because I might have accidentally set it to something other than their recommended bing.
And its a horrible reason too, Chrome sucks! Only reason i use it is because they successfully assimilated me into their ecosystem over many years and i dont have the mental energy required to ungoogle myself. I have come to accept that i am google's bitch.
I am so glad that I switched to Linux around 4 years ago. What a bunch of wankers. This just really shows that they think your computer is their computer to do whatever they want with. Microsoft is a malware company.
