And that is *exactly* why people should have thought "Hang on, If
TLS-everywhere is easly defeated by COTS products..."

Nobody is talking about it being a "viable replacement for TLS",
and we don't need a "viable replacement for TLS", we need technical
response that can be ramped up, and up, and up, in response to the
other sides increasingly desparate attempts to break it.

No, it won't be plug in, and no, it may not make people the same
amount of money as usual.  But it *might* push our political
agenda forward as a means of "civil disobedience".

Ohhhh yes, a lot of people said that, also in this group.  I've
personally heard Jacob say it both in public and in priave over a
beer.  And yes, I shared my view.

Rumours from local sources is that it simply took their webserver
down.  No rumours about the government decision having changed.
