Okay you are ready to take a stand for freedom!
You are going to use an OS that isn’t going to bend the knee and comply with age verification laws. I solute you, comrade!
Here are the likely consequences of your choice:
The Feds aren’t coming after you. You aren’t going to be out on a watch list.
What will likely happen is that if you try to log into your Facebook account you will get a message that says “Your Operating System is not currently supported. Your user experience will be limited to Groups labeled “Everyone”.”
That’s basically it. Your personal user experience will be limited to “kid friendly” areas of the Internet. (Same with apps and games.)
That’s the real driver of these laws. Facebook and other app producers know that the days where they can just shrug off child predators using their products is coming to and end. Regardless of your opinion on age verification is as a solution, child predators are a real world problem and it’s not just the parents fault. The platforms have some responsibility too.
Which is exactly what Facebook and the others specifically don’t want -responsibility for their own platforms. That’s why they are pushing for these laws that off load their responsibility onto the OS makers. Then they can just say “Oh, we don’t have any responsibility for this child being abused in our platform. We asked the OS what the user’s age was and the OS reported 18+. What else could we have done?”
So, that’s the consequence of you choose to use an OS that refuses to comply. You’ll just be relegated to the kid friendly version of website, games, and applications.
Right now? Nothing. Down the road, life in prison for terrorism. I’d suggest moving away from that jurisdiction
If their goal is to find an excuse to declare you a terrorist then there are much easier ways to do that that are already available to them. This really isn’t an efficient way to do that.
And, as best as I’m aware, no age verification laws anywhere threaten any consequences for the user. The consequences are only for the OS makers.
(Granted, the California law, at least, could be read to say that it’s the entity installing the OS to confirm ages, not necessarily the OS maker. So for most Linux distros that would shift the user age verification responsibility completely to the user installing the OS, but I’m not sure how that would work out in courts or whether websites and applications would recognize that. It will probably never actually be an issue that is adjudicated.)
