The main issue with Excel is that it is not multithreading in all operations. But for a lot of things it is the only software that can fit the bill.

Libre office feels a lot worse in to work in up to 8 hours a day compared to Excel and it is probably still missing some features like powerquery among others. I do need to test it again, it has been a while.

Then again I work as accountant so I am probably in minority of Excel users.

What legislation would do that? Would they want access to your messages or something?

Been there done that

And the worst part is? My job description doesn’t even include phone support. I am just the guy who is handy with computers! (I do get compensation for it, don’t you worry)
