There's a whole lot of people who don't have the luxury of just being able to assume a baseline level of trust, because they feel out of place for whatever reason. Think about what groups of people that might be, in the kernel context.
In the end they are set by politicians. Not for malicious reasons; politicians don't need to be malicious in order to make bad decisions, they have plenty of other reasons for that. In many parts of the US, surface road speed limits are quite reasonable, but freeway speed limits are ridiculously low.
You are correct, by the way, as far as I know, that the 55mph speed limit was originally an energy conservation thing. This was during the oil crisis of the 70s, when it was federally imposed. Ever since the federal mandate was lifted, speed limits have been creeping back up, but at very different rates in different states.
To give a comparison, in France freeway speed limits are roughly 80mph in dry weather and 70mph in rain (I say roughly because they are, of course, in metric.) In Belgium, and the Netherlands it's 75mph, although The Netherlands has introduced many variable speed limits (electronic signs based on congestion) and recently bumped it up to 80mph on certain rural stretches (rural by Dutch standards). Germany, of course, has no speed limits at all on many long-distance Autobahns (about 50% of the network), although in metropolitan areas, contrary to popular mythology in the US, they often do have speed limits, which go by the charmingly long-winded name of "Geschwindigkeitsbeschränkung," often shortened in colloquial speech to "Tempolimit." The de facto speed limit on the unrestricted Autobahns is 125mph, since that's the fastest unmodified German cars will go.
So did some technocratic bunch of engineers evaluate the conditions in each of these countries and decide that somehow some subtle difference of geography that Germans are capable of safely driving a full 65 mph faster than Hawaiians?
I doubt it.
May I also remind the reader that East Germany used to have a rigorously enforced 60mph limit that was rather promptly lifted after the reunification, which was by no means an event of particular relevance to traffic engineering.
Irrelevant, though. Sure, there may be no copyright preventing anyone else from ripping off his reformatting work, but that doesn't prevent him from charging for it. He just has to endure the risk that he may not get for it what he charges for it when somebody else rips it off and sells it for $0. This is analogous to selling a nice, commercially pressed DVD of a linux distro for $5. You have no protection against the next guy giving an equivalent item away for free, but there is no law preventing you from charging money either.
The software community is set up so that there is social compensation for open source labour. To a certain extent, the community of authors is the same way. The publishing community is certainly not set up so people are used to recogizing publishers for their contributions.
And some in the past tried charging for the result (rather than charging for support instead or as well, as RedHat and their ilk do).
It didn't work of course, but due to user education [the sort of people looking for Linux know they are likely to be able to get the same thing or better for free (plus media/transmission costs where relevant) elsewhere] rather than because it is wrong legally speaking, copyright or otherwise.
Which is completely irrelevant because whoever does have the original copyright has already licensed them to everyone under publicly available conditions.
The GPLv2 has made it clear something can be made freely available to the public, yet still have redistribution conditions. So, simply being "licensed to everyone" does not also grant distribution rights to everyone.
I'm not saying the GPLv2 withholds distribution rights; rather, it grants them conditionally, and if you can grant them conditionally you can withhold them.
Back when I did some small scale sysadmin work, I found that our CD/DVD burners were a lot more reliable as CD burners than as DVD burners. This seemed to be true both of the older Dell ones we had and the newer generic-brand ones. I had much better luck using CDs for basic installs and then fetching additional stuff from the net than trying to use DVDs.
- I also remember the CD burners to be more reliably, but that is my memory from maybe 5 years ago, I almost always use USB sticks these days.
- For local deployments (or even repeated installs due to tinkering-reasons), the best thing to have is a local http/ftp proxy (apt-get install squid).
Anecdotally, I've met many well-educated Russians who left in the mid-90s. I think, though, this was mostly due to fear for personal safety and a sense that their country was in a unrecoverable tailspin.
