Oh, absolutely. For some reason Apple seems to have filled Microsoft's role as the big bad legacy bad guy with vendor lock-in. Is it even possible to run macOS in a VM on non-Apple hardware with a non-macOS host yet? Microsoft provides free VM images for every OS and browser version you might want to test against, Google provides the Android devkit that works cross-platform. But if you want to target macOS or iOS it seems you're still stuck buying Apple hardware for $$$ to do anything. And don't even get me started on the lackluster support for PWAs -- at least the fallback for those is a web app that still works in the browser (provided you have Apple hardware to test it on). EDIT: Also Microsoft has moved React Windows into its official GitHub org and advertises it as an official way to provide extensions to Office.
