Weird, Gamemaker Studio and Floating Point are still free.
Might just very well be that there has been some suspicious activity on your account, and maybe you should change your password.

I took a peek at my log activity on ITAD and indeed 3 things were removed today: Bridge!, Nosgoth, and Life is Strange: Episode 1.

Life is Strange: Episode 1 I had already removed myself via Steam previously awhile ago because it prevented entering a giveaway for the full package here. Nosgoth I believe was not doing well (and was F2P?) and seems to have been removed from the Steam store, so it was probably some sort of automated thing. As for Bridge!, I have no idea what that is or where it even came from. I would remember having redeemed a key for it or something and it doesn't appear in my list of "licenses and product key activations" on Steam, so I have no idea there. There's nothing there that jumps out at me as suspicious.

From my Nosgoth game launch screen

Farewell
Nosgoth’s development has come to an end. The game has been shut down. You can learn more about Nosgoth’s closure at www.nosgoth.com.

Dead Island is still playable but no steam store page.
Savage: Resurrection seems to be renamed to Savage Resurrection (no : )
Bridge! is still on Canada's Steam as is Road to Ballhalla

RoShamBo: Starter Fighter Pack - Think this is dead now
Savage: Resurrection - Beta, this is obvious
Dead by Daylight: BETA - Beta, this is obvious
Hatred Editor - Eh
The Void - Still own
Nosgoth - Still own
Dead Island - Still own
Collider - Not owned in store, I was given this one by a site regular.
Bridge! - Not owned in store, I got this in a bundle I paid for, Humble Indie Bundle 12 - Edit, wrong game mentioned for the bundle. But still, I had this one as well, must have been another gift. This bloody sucks.

So two titles I'm missing? >:(
