That doesn't affect huge numbers of websites.

In the UK two of the largest ISPs - BT Internet and Freeserve - have
ECN-blocking
firewalls. So does theregister.co.uk for that matter. If I enable ECN
I lose
the ability to send emails to a huge percentage of the people on the
mailing lists
that run on my machine.

These ISPs will *not* change simply because 1% of Linux users complain
at them. They
have been contacted about this and they know of the problem. I doubt
they care.

Firewalls dropping ICMP does not make my internet connection practically
unusable. Firewalls
dropping ECN does.
