That was one of the hardest things for me to get used to when I moved primarily from Linux --> Mac (and it still makes switching between Mac and Windows annoying). Keyboard remapping helped at first but I was getting tired of inconsistencies so I just forced myself to relearn the modifier keys. Funnily enough, the command key and many of those popular shortcuts (eg cut copy paste) predates windows by several years. The story goes that windows wanted to use the same shortcuts, but PC keyboards lacked a command key - so they used control instead. Since windows was backwards compatible with lots of hardware, they couldn't require a key that didn't exist on most keyboards. Prior to that of course, Control has a long history of interacting with command-line based applications in Unix/family (eg Ctrl-C to cancel a running CLI app). Of course those same things still work in MacOS like they did in the older Unixes.
