I wrote a PR release for our startup and one of the British contractors volunteered to double-check the grammar. Oh boy, I got back was a massive annotated word document with red marks everywhere. I promptly accepted everything as if nothing had happened - I really do not care about American english (I am American) or British english and wanted to spend zero further effort on going back and forth. Even when accepting without qualms, he sneered at me about how American my english was, while completely unaware about the exact points you made! That said, I prefer British english for the most part but just being immersed in a land thousands of miles away, it is hard to not assimilate.
