I agree that's not a good reason to be happy.
Personally, I don't mind the acquisitions of any company. They are free to do what they want with their cash. Are Double Fine, and even Bathesda, now in a healthier position than before they were bought? Absolutely. Are Sony's purchases, yep.
Will I get to play the games day one on Game Pass now, guaranteed? Yes. Ok, that's cool for me.
In an ideal world Sony and Nintendo would also release their first party games on every platform as well, so we all have the choice of where we play based on power, affordability, social features etc.
It's a bit rich to comment on it on GAF though where the term 'Sony exclusive' is celebrated and used like it automatically elevates a game to God-tier status, regardless of quality. That's literally people celebrating that the games can't be played anywhere else.
