I'm struggling to see why anyone would root for Steam.
I've paid $10/month for a library of hundreds of games I can play on both PC and Xbox. We all knew that price was too good to be true but I've paid it happily for 5 years. We were waiting for the other shoe to drop and now it has. I've loaded up 2.5 years on my account at $20/month (the current retail price for Ultimate is $60 for 3-month cards.)
I've played countless indie games that I never otherwise would have taken a chance on. Even if I only played day one AAA games, the same $70 would get me one game on Steam for 2.3 months of the entire Game Pass library at the $30 price point or 3.5 months at the still-available $20/month price point. The game can't be resold on either platform.
Microsoft created a new business model that changed how I play games for the better. I can't see how the service isn't worth $30/month for 500+ games. (For a regular and not casual gamer.) This isn't shovelware like the Netflix library. There's a ton of high-quality games in there.
And I don't see how their price increase, which was inevitable and the timing of which was hastened by tariffs, has anything but a specious like to the merger.
Steam has done nothing but contrive a rent-seeker position for itself on an otherwise open platform. Maybe it's just because I'm old enough to remember a time when I could buy from the publisher without that middleman and click setup.exe for myself. And still retain the rights to resell and play offline without a middleman.
