I always use "scammy keys" on Steam and i never ever had any issue with, it always worked properly.
However, on GoG i do not use any of this, because i want to pay a fair price here.
Besides: A somewhat comparable version but still without GoG-Bonus-Items would cost around 7 EUR/USD/CHF using a "scammy" key.
The only thing i feel bad about Steam is "I still paid to much".
Those keys, in most cases, are fully legitimate (provided from Steam or MS), it works the same you may get a new Windows-License key. Officially they are telling you "scammy" but behind your back they are handing over "cheap keys" to countless key-resellers. Because it simply works... this is the basic economic rules... If you can not get someone to pay you more... then ask for less but PRETEND it is not from you. I tell you... Steam and MS, both are becoming dirty rich because of those "mass-key" sells and destroyed OS-keys from PC-part exchangement or broken Steam-accounts. A economy-model highly successful for them... but GoG is having a small "minority-gamer-base" so this model is barely successfull for GoG, because for this to work you do need "mass-sells", including DRM (so they need to buy the same stuff several times).
Sure you can still get Linux, no need to buy a new key as soon as a hardware-switch is breaking your OS-license: The problem is simply exaclty the same such as the issue with GoG: Many devs simply are not supporting Linux (or GoG).
I know... maybe hard to believe my surreal story... no need to believe me, stay with your own believe, this is better for you and your "innocent world".
