Yes, it's all a business decision.  That kind of antisocial thinking is
the sort of thing that has allowed all manner of bad guys to remain
attached to the Internet.

Yes, why not talk about rapists and drug dealers instead.  They're much
worse.  It's just that this forum ... isn't for that.

While I am all for increasing overall security on the Internet, the
reality is that there will often be devices that are attached that
are found to be vulnerable in new and intriguing ways.  Port scanning
is a primary method for finding these vulnerabilities.  To the extent
that an ISP might proactively port scan its own userbase, that's a good
use and probably a good idea (has tradeoffs), but bad guys finding
holes in random devices so that they can launch multiGbps attacks 
against random destinations is a bad thing.

If your idea of "operations" is to make your router work and collect
your paycheck for another day, then this discussion probably does not
make any sense to you and you probably don't understand the importance
of the issue.

If your idea of "operations" is to ensure the reliable operation and
uphold the performance standards of an IP network, then it should not
be beyond comprehension that allowing miscreants access to the network
is one of many things that can adversely affect operations.  If you
accept that the presence of miscreants on the network is a negative,
it shouldn't be hard to see that complaining about consistent and
persistent port scans from what is probably an identifiable host is
one way to make an impact.
