To be frank, while this person is just spiteful I find I an ungly mindset to blindly support devs like that as it's the same kinds of excuses that give legitimately scummy behavior a pass.
Granted I also don't feel like supporting the devs over the mobile version, but it's more on the principle that they are payealling a single version of the game when other devs don't or very least add other payed version rather than treating that one like it's special.
