Yes, it happens on a regular bases that *BSD's are ported to a 
particular platform or devices and that the necessary changes to make it 
work that way are not released back (eg Ironport mail systems). Other 
examples are extensions of other software to fill a particular need that 
are kept close for a binary only sale (eg Mammoth PostgreSQL + 
Replication).

There are numerous other examples, most of them are "company secrets".

Note that I do not have any objections to it, if I owned a company 
making profit on software sales (sale =! support) you sign a death wish 
for using GPL, if it's coupled with a device then things are different.
If you sell support, GPL is a wonderful way to maximize your income.
