Isn't T-Mobile Fiber violating their own TOS with CGNAT

You are not permitted to use your Device or the Service in a way that we determine:

• Operates servers for commercial purposes, uses applications which automatically consume unreasonable amounts of available network capacity, or otherwise uses the Service or Device for purposes other than the personal residential use;

That implies personal use is allowed, but CGNAT makes it so you can’t host a personal website, Minecraft server, etc. all personal non-commercial uses.
