Why is Source (2) far less used than other available engines?

Because Valve doesn't make games anymore. Once Gabe Newell found out he could sit on his fat lazy ass and collect infinite money from Steam, Valve hasn't made games. Steam, CSGO, Dota 2 and TF2 are the reasons why Source 2 isn't released yet, and probably never will at this rate.They print far too much money for zero effort for Valve to ever attempt a serious project again. They can just squander time and piss away money on stupid pet projects that end up being failures with no repercussions.

No one uses SteamOS.
There are dozens of devices that do what the Steam Link does for the same price or cheaper.
Anyone who already has an Xbox or PS controller isn't going to have much incentive to buy the Steam controller. Plus the cheapest good controller is like $20 on Amazon (Logitech F310). Why pay more?
The type of person who would buy a Steam Machine, is guaranteed to have a quality PC they use already. Why buy a "lite" PC that can only run steam when you can spend the same money on a PC that does everything?

I'll admit the most interesting thing they've done because of their lax attitude is push VR tech forward. But VR is still hella niche and won't be affordable or enjoyable for your average consumer for a long time.

Source 2 may be coming. Or it may not. Really depends on if Valve gets off their asses and gives a damn about games for once. With almost all of the writers now gone from Valve, as well as one of the level designers from Half-Life (John Guthrie) now gone.... maybe this will light a fire under the asses of who's left. Or not. Time will tell.
