I think a lot of companies implement OOB controls to curb P2P traffic,
and those controls remain in place even without congestion on the
network.  It's like making sure that nobody uses the company plotter to
print posters.

In my experience, a permanently congested network isn't fun to work
with, even if most of the flows are long-living and TCP-compatible.  The
lack of proper congestion control is kind of a red herring, IMHO.
