Regulatory capture is more than just lobbying, it's a hijacking of the regulatory process by regulated companies. In any case, lobbying is an attractive narrative, but I don't see the link between lobbying and the actual anti-competitive regulations. Verizon and Comcast didn't lobby to be forced to build fiber/cable all over vast swaths of ghetto. AT&T isn't lobbying for San Francisco to impose inane restrictions on where you can put fiber cabinets.

To put it another way: look at the regulations Google demands exemption from in return for building fiber: build-out requirements, slow permitting, etc. Did the incumbents lobby for these things? No. They arose out of municipal politics that have little to do with lobbying.
