If your system keeps people alive by relying on 100% Microsoft uptime, maybe they deserve some blame?

They do government and medical infra, those systems should be resilient but...

Absolutely.

I like to dogpile on M$ as much as the next guy, but this feels like a heavy strawman.

At no point is "keeping people alive" mentioned. Businesses use email for everything. Businesses usually don't care about where their email server is hosted. They just want to send emails. They shouldn't have to care either. I don't put blame on a business that happened to choose Outlook, one of the largest email providers, to host their email.

To be honest, Microsoft has much better chance of actually achieving that (almost) 100% uptime than your company's own IT department self-hosting things.
