You can't be too mad about the full port range. Residential ISPs blocking port 25 outbound (spam malware) and inbound (people installing mailer services as an open relay by default) contributed to tonnes of unwanted traffic.
I know there was an amount of collateral damage, but if you think about it, it's been many years since malware would get in user desktops and just send spam, largely due to this.
It's the internet, blocking ports without explicit reason is totally unacceptable. It's also in most cases since people will just tunnel their traffic over ports used by other applications, such as 80.
The right response is to contact the owners of the servers/services they're running and tell them to configure them correctly - if they continue to abuse them or don't show the technical skills, then that's another matter.
Blocking things like Windows file sharing ports by default is fine, as long as you have the option to turn that off. Other ports, including mail, should be open.
