Hey I have a real easy solution to that.
I'm perma banned because I had the gall to play modded MCC from the steam workshop on the day it released, before the moderation team knew modding was legal. I can't even log into Halo waypoint to get help from the Halo team.
I now can't play any Microsoft game, own an Xbox, or use game pass and I refuse to make a new account on principle.
I was pretty high up in Actuarial at a fortune 500 insurance company. At my old company, if you went to a competitor, your account was shut off that day and none of your unused time off was paid out.
You don't owe your company anything they won't reciprocate. The company will continue to operate no matter who leaves under whatever circumstances - don't fuck yourself for a faceless corporation.
If you know your manager is very employee-centric and you have a great relationship, maybe approach it with caution, but otherwise, your interests should always come first.
