There's really no "Microsoft" borg that's "forcing" anyone to do this. There were just some core problems that were unfortunately missed. Not anyone's fault in particular, but a shared responsibility between devs and managers, and both devs and managers are doing everything they can to resolve the problems as quickly as possible.
Whenever there's weekend work like this required, everyone's always super appreciative of whoever does need to do the extra work - meals covered, extra vacation offered, etc. It's pretty nice actually whenever I've had to do it in the past. Honestly the working conditions and respect for work/life balance is one of the main reasons I've not considered working anywhere else. And that includes rare situations like this.
