Google for "acrobat reader file locking" and you'd notice that

Surely that evidence falsifies your claim? If it's possible for
another reader under the same operating system not to lock the
file, then the locking cannot be a property of the operating
system, still less of its legacy? In fact, it cannot be: just
look at Windows' Notepad, which does not lock files it opens.
Opening for writing locks the on Windows.
Do you mean that all Windows software capable of editing document
files locks them? Sorry, but that is simply untrue - as I
suggested. See http://en.wikipedia.org/wiki/Notepad_(software) :
"Notepad does not require a lock on the file it opens, so it can
open files already opened by other processes, users, or
computers...". So this is surely not about any difference between
operating systems? In any case, file locking is surely in general a
Good Thing, isn't it? LibreOffice locks document files against
opening in another instance of LibreOffice in its own way (under
whatever operating system). The question here should surely be
whether you want a PDF reader that is capable of annotation (and
therefore of writing to document files), and if you do, how you
want it to behave.
Linux informs that the file was changed or removed if it editing
it, that models the real world.
So you mean that I can spend a couple of hours editing a file, only
to discover when I try to save the result that you have been
editing it as well, and I have the choice of either overwriting
your changes or abandoning mine? That's not part of any "real
world" I want to inhabit.
No, you get the option to either 'save as' or quit without save.
This is also true in some traditional editors in Unix/Linux like emacs.
But that has exactly the same problem as I was suggesting. I've been
editing for a couple of hours, expecting to be doing useful work,
only to find when I come to save that you have also been editing
independently. Now either of your options is unsatisfactory: either
the work that I have done is wasted or else we end up with two
separate documents and the job of somehow merging them later. I
needed to know before I started editing that my work would be wasted
and that I should hold back until you had created your next version.
A lock on the file enables any user to appreciate the problem in
advance - which is not dissimilar to the original suggestion about
exporting as PDF.
