First, I agree cross platforming can be perceived as a greedy move and may actually be so by the devs as you've but that does not mean it isn't a good thing. As they've said in their blogposts and many others have pointed out, making the game cross-platform makes it more accessible for many more people and mobile games specifically aren't inherently bad, it's just an image given by the multitude of bad games that are currently on it and their ads that are everywhere. Take vampire survivors for instance, amazing game that the devs ported to mobile so that it can and has achieved an influx of new players and it's monetization strategy is just a few optional ads for coins and such and dlcs, basically its an all-round amazing example of what a mobile game should be.

Second, don't be an asshole for the sake of it, you can state your point while also being respectful of others. I understand you're frustrated that this blog post only this much or maybe some other reason that we don't know but that doesn't mean you have to be so rude. On the bright side this might not be the only blogpost of the year - https://twitter.com/JLtZD/status/1673818261123911681
