Technically, you're quite correct. Politically and socially, it's a serious
problem. This is a *BIG* issue among my "Internet libertarian" friends. They
absolutely do not want their ISP's interfering in any way with their home
connectivity

I'm not really an "internet libertarian", but I'm against arbitrary port
blocking because it breaks things randomly.  I've already had the
experience of trying to set up a custom service on a high-numbered port
and having to play "minesweeper" with my users, trying to find a port
number that no one's ISP was blocking outbound connections to.
