The PC sector of gaming has always been chaotic. This is in part due to its open nature. There's no single company with control over everything that happens. There are platform leaders, naturally, but though decisions made by Valve and Microsoft and Blizzard and Mojang and Riot affect millions, they don't affect everyone who plays games on PCs.

We could be wrong, so feel free to stay updated on video game news and then mercilessly make fun of us in the comments when we turn out to be completely wrong.
