Actually, I don’t. But I have to ask: if they can make it illegal to circumvent copy protection to do something you could legally do without the copy protection, then why can’t it be illegal to circumvent pop-up blockers?
Hmmm… considering that pop-up blockers are arguably a security feature, could the US DMCA be used here?
You obviously do not understand modern American law. The DMCA states that non-corporate entities (aka “consumers”, “voters”, or “human beings”) are prohibited from using or modifying any software or device related to security, privacy, or intellectual property. In other words, no matter whether you are attempting to access someone else’s content, or prevent someone from pushing their content at you, it is illegal for you to do anything (or think or talk about doing anything) which interferes with this process.
When in doubt about whether it’s legal for you to do something under the DCMA, you can always use this simple rule of thumb: do you have more money than the other party? No? Then sit quietly until instructed how to pay.
