One: Can you give me anything newer than 2016 for the SOX issue? I can't find anything outside of a few years around that (2013~2016), and as far as I can tell, the issue was teh feds actually overreaching their reading of the law. That happens a lot. Overreaching, not because of the whole felony/crime thing, but because SOX explicitly declares that it's purpose is to keep both enterprises and individuals from commiting financial fraud.
I can't find anything newer than that case, and everything I find for that, and before that, looks like the classic cop trick of arresting somebody for no reason, then charging them with resisting arrest/obstruction of justice/breaking federal equipment when they fight back the illegal arrest.
Two: The whole cookie deletion being a crime I can't find anywhere outisde of the few links you provided. And only as speculation, based on the exact same 2016 case. Again, under the same set of overreaching of laws: They alleged he deleted evidence of a federal crime related to terrorism. Nothing on reading extra documents on an online journal.
I've never consumed such a site, so I never think of those. I can tell you that yes, in such a case, if you were doing that? It would probably fall under a crime. I don't know if it would be a felony though, because it would fall under a completely different law (Copyright), and that would be probably some kind of tort under civil law (you're hurting their bottom line by not paying what you should by circumventing their DRM-ish attempts). In such a case, well, you ARE commiting a crime by deleting the cookies intentionally to read extra. Any other reason is easily winnable at court (again IANAL, so YMMV).
Three: Your interestingly insistence on guilty before proven innocent is jarring. Mainly because the whole innocence/guilt thing is very complex, and no, it's always innocent first. This is like talking with a FLERfer about the scientific method. It is first the due process of the people bringing their charges against you to prove there's cause enough to believe you might be guilty of the crime. Then, it's your responsibility to show them they are wrong. That's how it (generally, more or less) goes: They say you did something bad, you plea innocent, they try to prove you're guilty, you try to prove they're wrong, the judge and/or jury decide where the sword falls. The law is explicitly and markedly on the defendant's side, and the prosecuting side has to prove a lot more than the defendat's for most things.
Four: I don't really bother too much to hide my electronic fingerprints. Fact is, I have a lot of other things that would allow a big agency/state agent to identify me if they wanted floating around the internet, to bother obfuscating how I write the half dozen post I throw in a minor porn forum when debating the applicability of SOX to how much porn you consume. That includes a very big electronic presence going back decades.
Five: The rootkit thing, I've said the exact same thing: being in the EULA, or not, is irrelevant to Copyright and laws. That kind of thing was rampant at the turn of the millenium. And no, sorry but you're completely wrong on your interpretation of case law from 20 years ago.
If the rootkit had been illegal to be installed into your computer, then you had two recourses: suing Sony (I know), or deleting the whole product. The fact that you commited a crime, because somebody else commited a crime against you is not a valid legal excuse, unless your actions fall under another law that states it's not a crime to commit them (for example, killing someone in self-defense).
And, also related to that: I do know how ridiculous the whole DRM part of the DMCA is. It's "designed" to cover everything, from a physical button, to an AI that self-governs a server. Anything. And it was pretty much written by the companies that use such DRM. You still have two options outside of pirating the software: sue them if it's illegal, don't use it if you don't care for the DRM.
And yes, I understand the irony of saying such a thing in a pirated porn forum, but at least I won't be a hypocrite and say that I'm not breaking a law because it wouldn't be a crime if the law didn't exist, if I were to get caught breaking a law, that is.
That's how laws work: They set the rules. You don't like them? They are unfair? Do something to change them, instead of complaining in a porn forum
