G2A er blandt de digitale butikker der har været forrest i skandalerne om det grå game key-marked, der angiveligvis tjener penge på udvikleres bekostning, og er ansvarlig for svindel i stor stil. Det synes udgiver og udvikler Gearbox tydeligvis ikke er et problem, for de har indgået et nyt partnerskab med G2A om nogle Collector's Edition-udgaver af Bulletstorm: Full Clip Edition.
Ifølge Kotaku har dette gjort at Gearbox er kommet i massiv modvind, og det er også mærkeligt at de har indgået en aftale med en digital butik om produktionen af fysiske udgaver af et spil.
Blandt de største kritikere er den berømte Youtube-personlighed John "TotalBiscuit" Bain, som har afsløret via Twitter, at han ikke længere vil dække Gearbox-titler før der er kommet orden i sagerne:
"Pulling coverage plans for it and future Gearbox titles. No support for crooks. A message must be sent that greymarket havens for fraud and theft will not be normalized in this industry. You know what I call "work with us and we can help your keys not get stolen and sold on our site"? A protection racket."
Kotaku har spurgt Bain om præcis hvad han mener, og her svarede han:
"G2A has offered its own payment system as a 'solution' to credit card fraud and mass-chargebacks which cost indie developers and retailers huge amounts of money and put them at risk of being blacklisted by the worlds major credit card companies. A company can decide to work with G2A directly and use their payment solution and API, from which G2A takes a fee. This has been offered to companies such as TinyBuild who claimed to have lost hundreds of thousands of dollars in revenue due to G2A as well as smaller startup retailers such as our partner chrono.gg, who also suffered significant credit card fraud and chargebacks early in its life. When they approached G2A regarding this, they offered to give them insight into who was selling stolen keys from chrono.gg but only if they switched to using their payment system and API."
"G2A is providing a 'solution' to a problem that they created and continue to facilitate and profit from both the solution and the fraud. G2A is essentially saying, 'That's a nice game you have there, it would be a shame if something were to happen to it.' That sounds an awful lot like a protection racket to me."
