Honestly Minecraft is wholly off my radar... I have never owned it and not played a moment. I have nothing against it just never been a big Sim/Management/World building fan. Also style of the game doesn't interest me. (just a full disclosure)
And I'm not dismissing the twitter posts in the least but cmon they are more antagonizing then they are welcoming. Just saying if that's how I was being approached to agree to something that doesn't really benefit me I'd say "Sit on it"
Yes Sony should opt for it from a consumer standpoint, and there's tons of things that all platform owners do that really irks me... I have plenty of gripes with Sony be name changes, PS1 emulation, the way they handled the Vita, the ability to not communicate better with fans, terrible horrible customer support, and an inability to fund 1st party JRPGs for the last two console gens...
I just tend to comment from common sense and not what I'd like. There's a lot of things I'd like but I'm realistic and know what is and isn't really logical from a business standpoint...
The Twitter posts are antagonizing because Sony in this topic are the antagonist. They don't use aggressive language, just simply "we would want it to be crossplay". Without that, people would still be trying to claim MS was the holdout (which people were selectively doing for Fortnite right up to yesterday). Behind-the-scenes attempts at negotiation have clearly happened for a long time before it gets to the point of us being made aware. No different to Bethesda mods and EA Access. Epic didn't just get up on the TGA stage and rant about not being able to crossplay between consoles without actually attempting to make it happen privately first.
Your disinterest and/or ignorance of Minecraft and the situation surrounding its crossplay is squarely on you if you're going make claims that MS haven' or tried doing "legitimate business" with Sony. They publish the biggest game on the planet on their hardware and offered crossplay and feature parity with the latest version of the game. Sony disallowed it. "Oh, I don't really care for Minecraft" has no bearing on your previous statement of:
let's see MS try to do any kind of cross promotion or deal with Sony that just fair to both and then let's see if Sony is the same stick in the mud... then I'd fault them... then I'd scoff at for the players...
... this already happened, Sony was already the "stick in the mud" regardless, and you still hold the same position.
