Xbox and PlayStation. The "problem" is that you want to game on your PC, not that there isn't another viable option.

I’d be happy with console gaming if there was a $2000 console with mouse and keyboard controls. I don’t want to play with a controller and I don’t want 3yo hardware.

Arguably, gaming on an Xbox is still gaming on Windows so it's a funny option to pick if the goal is to avoid Windows. ;)

Can you point me to the console version of Dota 2?

I mean, that particular game does run exceptionally well on Linux. I think, even quite a bit better than on Windows, unless your GPU's drivers for Linux happen to be shit, of course.

But yeah, the overall point still stands. If you have a particular game that you don't feel like you can substitute and it's not available on a platform that you'd like to switch to, you're probably not switching to that platform.

Mouse / Keyboard input. Though, that is opening up more and more nowadays.....

Xbox One supports it natively (via good old USB) as of a "silent" update a year ago or so. Not all games support it (for various reasons of engines and developer preference), but you might be surprised the ones that do.

I know, I worked on the project that enabled it. This was more to the latter part of the comment, that games will not be designed around that modality and would always be altered accordingly. Not necessarily a downside for everyone (and more of a presumption), I should point out. :)

I figure that so long as there are PC-using developers building the engines, keyboard/mouse support will make its way into a lot of Xbox games naturally (because why disable something that works great for testing/debug?).

I've also seen enough people that are quite skilled with a controller that they perform better than the average keyboard/mouse player, that I think we'll see less people worry about cross-modal play.

I love having the option to game with an Xbox One controller on my PC, and I love that keyboard/mouse preferring players sometimes have that option on the Xbox. Let everyone play what they find fun.

I've been playing a bunch of Sea of Thieves lately, and it's almost surprising there isn't a controversy about cross-platform/cross-modal play, and yet it is open PvP. I don't feel like it matters if I'm using keyboard/mouse or controller, much less if an opposing player is, and that's a weird sort of magic. (It matters more if the opposing players are jerks that don't follow the Pirate Code.) Props to Rare for pulling that off, and maybe that will be increasingly a thing. (The Gears of War cross-platform/cross-modal playlists have gotten good reviews as well, from what I've heard, though I've not specifically tried them.)

Why game on a console if you can afford to do so on PC?

There's also game development, with both art and engineering departments running windows.
