I personally don't see the "Eureka!" moment that big tech apparently does in moving EVERYTHING to the cloud when they struggle to design safe and reliable services as is. The whole cloud stuff just kind of says "sure it will be a privacy nightmare rife for exploitation from bad actors, but THINK of the money we could earn from it in the long run!"

If he's spending so much time playing it in person AND online then I do agree the time he's playing vs. spending time with you is alarmingly disproportionate, especially if he is spending some of his leisure at home but opts to play D&D online with friends rather than sparing it to have some quality time with you.
I think a deep discussion with him is in order. But no, you are not in the wrong for wanting him to dedicate some time out of his schedule to you.
Some folks really don't understand they can absolutely get what they want out of the fediverse, they're that accustomed to the limits of the more mainstream options. It's whatever they want it to be. If you're tired of not seeing enough of something, there's nothing stopping you from creating your own instance or a community within a pre-existing instance and rallying others to engage. You're always bound to find someone with a few similar interests around.
It will never grow or change if nobody is willing to directly participate in what they wish to see grow or change.
Corporations will literally do anything except act remotely ethically towards consumers.
