I put the blame on Microsoft here. I am more pro-ARM than I'm pro Apple; I had a surface pro X and ended up giving up on it because Microsoft has put zero effort into enticing developers to make ARM versions of their apps. Google drive still doesn't have a functioning app (!!) for Windows on ARM, which at this point has existed for over 10 years. (Emulation doesn't help here as it needs drivers).
In contrast, Mac has had apps since basically day 1 of Apple Silicon, and ARM support in Linux has been pretty good for years.
If they're getting money through micro transactions they can charge absolutely precisely £0. I can't be bothered paying for a game that isn't complete.
