I’ve said it before, and I’ll say it again: The ONLY reason it “can slow Internet connections” is because the ISPs advertise a bandwidth that is much higher than they can handle should all subscribers actually use that bandwidth they paid for.
If they have a problem with P2P then they should change their billing plans to reflect the reality of the situation rather than lying to consumers.
I totally agree. I'm a huge fan of P2P software and technology. If an ISP has a problem with it, they should say so up front in service agreements and not mess with subscriber bandwidth. At the same time they shouldn't falsely advertise promising lots of bandwidth to everyone, while gating some users behind the scenes who running P2P apps to make it happen.
