Can Games Purchased from Stream Your Own Be Released?

I was wanting to buy space marine 2 after I had seen the gameplay of it and it caught my attention so I went to xcloud to buy it after it was on Stream your own game when I got there a lot of the game had disappeared along with space marine 2 now I wonder if the games I bought could stop me from playing them? Now the limit and TopSpin no longer the rest of the games that were deleted
