I don't know if it has anything to do with Dominion or Microsoft directly

I think Dominion's specialty, even though they'll never admit it, is providing shoddy voting machines that are easily modified.

Think about it. You'd want to use a dominion machine to easily manipulate an election. Dominion knows their machines aren't secure, but they'll gladly sell them to you and let you do whatever you want to them

Dominion can make bank and then plead ignorance about the security of the machines, leaving both the corrupt states using the machines and dominion themselves satisfied

I don't think Microsoft did anything but provide their software. They wouldn't know what it was going to be used for
