Now you're back to "sheep". Don't assume that "technically
inexperienced" equates to "clueless".

Security theatre is generally not positive, but again, security is
never absolute and you will always be able to find an argument for
doing more, and someone who will argue that failing to do so is, yes,
arguably bad. Everyone has to draw the line somewhere. Tor has done
so.

We're going in circles on this now, so this will be my last repetition
of that particular argument. As I've said, I think we agree there's
room for better education, but just differ on details.

That's a list of projects Tor is involved with. It's interesting but
there's no context - someone who knows they need the tool is already
most of the way there. Helping people identify that the need the tool
at all is the part I'm interesting in.

At a guess, it's because Tor is more actively involved in Tails than
in Whonix. But that is just a guess. Have you asked the maintainers?

Very different issues, I think. I'm sure you disagree; I'm not going
to debate it.

Yes, I do. Systems get attacked, and are updated to thwart attacks.
Tor does this - that is not a fail, that's the normal security dev
process. Don't assume that nothing is happening - it's not like Tor is
not actively researched and developed.

Have you updated it to account for subverted VPN providers? Advising
people to use VPNs which may have been subject to national security
letters is arguably bad.
