Or get business class AT&T if you like them so much. They don't block any ports on business class. For residential service they've already been blocking port 25 for a long time. It is not surprising that they are blocking 8333 as well, probably even mistaking it for a botnet command and control channel.
Not just port 25, but telnet/RDP ports, things like netbios, basically any port that can be or is being heavily abused
only on bitcointalk could this action be seen as a conspiracy
