I finally got so fed up with Edge quietly changing my preferences back to their defaults I decided to completely stop using it. I have an MS account, Office 365 for work, etc. I thought, this is great, I'll continue using Firefox for personal and Edge for work, it integrates with my company account, that's neat.
But no, they can't leave well enough alone and just let me use my machine the way I want to. I don't want news on my work homepage, heck, even the weather widget bugs me because I can't turn it off.
So I found the Edge executable, added "off" to the end of the file name and now it's just sitting there, broken. I'm sure some update will come along and "fix" it for me but for now this slightly passive aggressive but mostly useless reaction on my part made me feel slightly better.
I'm not the same MS hater I was in the 1990's but sometimes they make it hard to forget that time, wish they would learn to get out of their own way and mine.
