where I live, my ISP does not allow using any third party routers for broadband use. Additionally, other devices like STB and other IOT devices sold by the ISP now refuse to work entirely if it detects any other routers being used. Somehow this feels wrong to me. I wonder how bad the situation is elsewhere?
For instance, LinkedIn loads google's STUN on the login page. I understand the need for STUN for sites like google meet or zoom, but some sites clearly don't necessarily need it.
