... it boggles the mind to think that because they use Mac's to develop on, they never tested things on other devices.

Until very recently (the arm switch) it was possible to use a Mac and test on every major (and most minor) desktop environments and with a little effort, both major smartphone platforms. From one physical computer.

They obviously knew what their customers used and therefore cared about and then followed the happy path.

Keep in mind this switch isn't because they see a sharp uptick in Windows users, it's because they are realizing that while Apple is a nice cushy baske, it's not so good that all of their eggs are in it.
