If this change has taken place, perhaps a separate thread on the subject would be a good idea.

Yep, this does seem to be these case. I would say it was very very silly to have the default as off, apart from the fact that not everyone has firewall protected routers, this causes extra traffic on one's connection if there is constant port probing.
One of the claimed benefits of a PN connection is the ISP provided Firewall.
The average punter wouldn't understand all the complexities nor would they realise it was off, and the previous default low setting usually suits most needs.
I would request that 2 things occur.
1) The default be changed back to Low ASAP.
2) All new & existing customers that have changed or signed up to new producst be sent an e-mail advising them of this and to check their settings suit their needs, with a recommended default of Low.
