From the individual's perspective Microsoft might seem like the better choice if they can achieve higher availability, but the societal cost is so much greater when the one basket you've put all your eggs in breaks even if everyone holding their own egg on average results in more broken eggs per year.
> I dislike Microsoft as much as the next guy, but many businesses impacted by these outages are completely innocent and don't deserve these consequences.
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.
