(Assuming that was for me...)
By "hiding" I mean, "taking refuge in some place, where you think Big Brother
can't see you, and won't get you".
(Since that, if we just try to "hide" from him, and not fight him, he will
dominate society in such a way that he will, definitely, end up being capable
of actually knowing everything - and be impossible to fight, any more.)
I didn't mean "not trying to protect, within possible, our communications,
and preventing Big Brother from reading (/listening to) them".
Also...
I've, in the meantime, posted a reference to one of the most secure
alternative forms of communications that I know of, which has been
recommended by (political) authors who have build a (very) credible
reputation, over the years - and, whose work every so-called political
activist has an obligation to know about.
