Yes... in the same sense that if a user bricks their own system by deleting system32 then Windows shares some small sliver of the blame. In other words, not much.
Why should Windows let users delete system32? If they don't make it impossible to do so accidentally (or even maliciously), then I would indeed blame Windows.
On macOS you can't delete or modify critical system files without both a root password and enough knowledge to disable multiple layers of hardware-enforced system integrity protection.
the difference is you can get most of the functionality you want without deleting system32, but if you want the super secure version of NT, you have to let idiots push untested code to your box.
linux, Solaris, BSD and macOS aren't without their flaws, but MSFT could have done a much better job with system design.
