Calling this "paying to unlock ports" is disingenuous. I'm also a T-2 customer and have run into this before. They block ports on dynamic IPs, but if you pay +2€/mo for static, this is unlocked. This seems reasonable. If you're not paying for static IPv4, you're paying for "internet access", whether that's a rarely chaning dynamic IPv4, a constantly changing IPv4 or full CGNAT.

Would you also say your mobile phone operator is violating net neutrality by putting you behind CGNAT that you can't forward arbitrary ports through? You can pay a bunch of money to get a private APN and get public IPv4 addresses. Would you call that an unblock fee?

I've been told there's a law that my mobile phone operator has to turn off all firewalling on my connection if I ask.

I don't know about that law, but GP's point was that you don't get a public IP anyway, firewall or not. And with this NAT in place, you can't ask them to forward specific ports to your equipment.

In France, CG-NAT is getting widespread even for fixed, FTTH links. I'm typing this connected to SFR, which provides a static IPv6 /56, but IPv4 is behind CG-NAT. I can't host anything on IPv4. I think there's an option to get a fixed, internet routable address, but not on the "discount" plan I'm on. I hear you maybe can ask support to get you out of CG-NAT, but that doesn't seem very reliable.

Free (local ISP), by default, doesn't give a static IP for fiber, but you can ask for one for free through your online account page (you just need to tick a box).
