Linux

Nope, that's not how it works on Linux, even if someone introduced the most heinous breaking change people would just not update until things were fixed, in fact the update is unlikely to do that because things are tested before being pushed. If someone were using latest of everything by having something like a Gentoo system with everything building from git maybe that person would be affected and he would have to rollback to an earlier version and keep going for a total downtime of 1h tops, and that is if someone was using the most stupid way possible in production.

The main reason why this will NEVER happen to a server running Linux is that updates are not automatic, i.e. they get triggered manually, so if there's an issue upstream you don't update, and if you encounter you rollback. The issue is not that Windows had a broken update, that can happen and it's fine, the issue is when the OS forcefully installs that update and breaks your system without you doing anything.

And yeah, I know what I'm talking about, I worked as a software architect for a large website for a few years and now I work as a software engineer for the servers of one of the largest online games.

Edit: re-reading your post, I would like to ask you how would you build this critical infrastructure with Windows? Because independently of how you answer it you would have been affected by this.
