They kind of are releasing it to free, just hiding it. You see, they made CS2 not even bother with the whole serial process and just say "oh hey thats a key lemme open CS2 for ya" and basically what it means is that any serial code will work, and since there is no activation since there is no servers it is now akin to giving your Blockland key away, except without all the downsides. IE someone on the internet could legally tell us a serial code, which everyone could legally use and it would be essentially free.
