I work as a fiber PM for the second biggest ISP in the country. Our biggest innovation in about 50 years just took place in 2017 - fiber - and investing heavily in fiber over coax for the very first time. My job prior to this was as a software implementation PM.
Infrastructure innovation does not happen at even a fraction of the pace of software. ISPs have to pivot their entire businesses (workforce, capital, product offerings, contractors, etc.) just to accommodate a single, major update in 50 years.
Salesforce (for example) rolls out a massive backend overhaul on an annual basis with incremental updates every month.
With fiber, everything must now be built new over the entirety of the country. Massive relocation and layoffs take place, new contractors are hired, sales staffs are re-trained. That's the cost of an infrastructure update.
You're out of your element here, Donny.
