The other issue is jurisdiction over telephone pole infrastructure.

Google ran into a legal issue with localities who had given full control of telephone poles to the ISPs. They were technically considered private property even though the poles were planted on public soil.

Google was basically being told that if they wanted to expand their Google Fiber internet service, they would need to have their own poles built as they couldn't run lines on what already existed.

I believe Google had laws changed locally in a lot of places as even the local governments were tired of the ISPs and their bullshit.

But this is one of those reasons why ISPs have monopolies in many places. Getting infrastructure built is a fucking nightmare.
