It doesn't fell open when you read the specification. There's a whole
page dedicated to copyright bullshit right after the table of contents
(you may not this, you may not that, etc; e.g. "receipt of this
specification does not convey any rights to [...] use [...] anything
that it may describe in whole or part").
