Aren't there laws against arbitrary denial of service?

For a service you don't pay for? No.

Light rail systems are not limited to 10+ minute headways. Modern UK tram (streetcar) systems have services at frequencies of up to 2 minutes on busy lines at peak times. (E.g. Manchester Victoria, where 6 routes each with a 12 minute frequency pass along a common section).

Also this:
http://en.wikipedia.org/wiki/Light_rail#Capacity_compared_to_roads
Indicates headways of as little of 2 minutes, and vehicles can have up to 4 cars (which would match the capacity of your 4min/8car heavy rail example.

and then crying when they had try to reorder them to get their program to work

That was the tears, later came the laughter when CA's mainframe Librarian product would state:
"-END CARD MISSING - MAKE SURE DECK WAS NOT DROPPED"
Even though it was reading from disk or tape...

(This was about 20 years ago, As far as I know it still does this to this day)

Also, it buys them some limited but still effectively free publicity (which I don't begrudge them at all, as long they give the kit to a museum when they're finally done with it).

Linux ? yes I would like to - but even with LTS versions I need to re-install the OS every 2-3 years.

5 years support now for Ubuntu and Mint LTS

13 years for RHEL/CentOS etc.

and you go from a place where people eat stodgy well-cooked roast beef

"Stodgy" never describes beef (or any meat). Stodgy means stuff like Yorkshire pudding (savoury) or Bread pudding, or Spotted Dick (Sweet).
Stodgy is lots of carbs.

The majority will adapt quickly (if you are starving, food is a *very* powerful motivation); a minority will go postal.

Moreover, it is in FSB's interest to have people believe that they are more capable/powerful then they really are.

You don't state why, but I'm guessing for intimidation/control purposes. Which is certainly a point.

However:
It is also in the FSB's interest to have people underestimate their powers so they will be incautious, using systems they believe are secure which the FSB can crack..

It is also in the FSB's interest to have people have a roughly correct idea of their capabilities, because when their real capabilities leak out (as is fairly inevitable), people will neither be horribly shocked at their intrusiveness or surprised as to how weak their capabilities are, so they will avoid unwanted criticism and attention.

You obviously do not understand open source. If a protocol or software gets big enough that a lot of people use it, it will also get a lot of developers looking at it. If a backdoor is written in, eventually someone will find it and report/patch it.

And further to that, there will also typically be a handful of uber-devs who get to accept or reject patches - getting a rogue patch past one of these people, who know the code better than anyone in the entire world, is going to be near impossible.

Besides, it's spoken like that in weird languages like english.

You mean *US* english.
In the UK virtually everyone says "(The) 8th of March 2013", not "March 8th".
and we use DDMMYY not MMDDYY (and it's really annoying that 98% of software packages can use DDMMYY but about 2% insist on MMDDYY)
