That's because many (probably most) Linux bugs are dependent upon the
hardware which they run on, and developers cannot reproduce the failure on
their hardware.  Other software products don't have that problem.

That being said..  four or five years ago, developers would often work
closely with the reporter working out why the reporter's failure was
occurring.  Several days of back-and-forth.

We dont' do that as much nowadays - there's a tendency to

a) throw the problem back at the reporter, often asking them to bisect. 
   If the reporter is running a distro kernel (eg: Fedora) then that's
   quite hard, and often isn't a think they have knowledge to do.  So
   they'll just disappear.  Or

b) just ignore the report altogether.
