No.
UPD. Sorry, was distracted.
The whole point of this topic is information gathering (at least as little as we can). So regular users gathered as much information as they could from the beginning of the year about this game, that's when they stopped working. Why - we can only guess, but if there's an option to set an expiration date when generating Steam keys, that's most likely what happened. Same with Solar Flux also this year. All the other games are harder to keep track of, but this definitely happens a little bit every year.
