No, I didn't purchase a game from g2a and Steam never removed it from your account.

I purchased multiple titles from them and experienced great satisfaction. I also acquired an AV key that performed exceptionally well!
I've purchased many games from G2A, and even some operating system keys back when they offered 8.1 pro keys at low prices (still checking if they're available now). The only exception was once when Steam took away a game I received as a gift through G2A instead of just a CD key.
They offered a security insurance for just 70 cents. Including it in your purchase can protect against potential issues.
