PowerToys Run is more featureful than Spotlight and should be compared to Alfred or Raycast. Basically, the biggest differentiator is whether you can write a custom plugin for it or not.
This comment is pretty amusing, seeing as Apple "Sherlocked" Watson with the predecessor to Spotlight
It's a community project and Spotlight wasn't the first app launcher either.
A lot of Mac users are oblivious to anything outside the Apple ecosystem. To them Steve Jobs basically invented sliced bread and everything else is a copy. Good thing the industry didn't also copy Apple's OOTB window management.
You mean they both copied 9menu (1994) from Bell Labs?
