I feel like it’d be wise to wait for further developments. Valve is notorious for being horrible at communication, but even then it’s rare that they do something like this without some sort of reason. It still sucks that Valve shut this down after 8 years, but it’s hard to know anything for certain until either side comes out with more information, especially with how stupid Valve’s legal team can be sometimes. Could be that they just backpedal and say it’s alright in a few days, who knows.
Of course, trusting Valve is always as risky as trusting any other corporation, given they have a bit of a track record with tolerating and even outright allowing gambling with skins, but this could easily be their legal team being overzealous yet again as well.
Both jus soli (citizenship by birth) and jus sanguinis (citizenship by blood) exist more for historical reasons than because one is better than the other. Both are simply a way to try and make citizenship a more clear-cut thing, because it’s as close to being a made-up thing as you can get, especially in cases such as parents having a different nationality to the child (which is even more confusing when both parents are of different nationalities).
Jus soli is more common in the Americas due to various factors, including an incentive towards immigration from richer countries during colonial times and the various movements towards emancipation of the enslaved peoples a few centuries later, but the fact remains that neither system is any more arbitrary than the other. Jus soli is often favored because it simplifies things like immigration and asylum seeking and reduces statelessness, which is still a significant issue that affects millions of people worldwide, mostly around war-torn areas.
As mentioned in another response, enfranchisement is also a very important issue that jus soli resolves, although a significant part of it is also due to other, unrelated citizenship laws that may not necessarily conflict with jus sanguinis.
