Wrong, there are scaling problems. Have you ever worked at both a very large and very small company? Were things that were easy at small companies much harder at large ones?
Taking politics out of it. If you wanted to start a 25gbps project today, who do you think could get it done quicker. A small local municipality with a few network engineers. Or getting a Federal agency to do it?
My money is on the municipality.
The municipality is a more concentrated interest, and more motivated to deliver on a solution that works for their constituents.
Compare that to the federal government needing to execute a national “Interstate Highway for broadband” mega-project. The federal government can and has executed these kinds of projects, but it needs to consider different things than the municipalities.
Extending the highway metaphor, a smaller municipality can pave local roads just as quickly as the federal government can build highways.
Efficiency is not a perfect function of government size.
In theory this is supposed to be to make sure someone is serving rural areas but in practice it's because the incumbents don't want new challengers showing up to provide better service in the areas where it's profitable to build a competing network and so lobby the government to saddle them with a huge barrier to entry.
The wonderful Minneapolis-local fiber ISP US Internet recently got bought out by T-Mobile (Deutsche Telekom) for example.
Wave Broadband in the bay area got bought by private equity.
All around the country you'll find local or municipal cable companies that got sold to the big players, Mediacom, Comcast, etc.
So I think it is hard to compare small and big. For one company things are easy that are hard for the other and vice-versa.
I don't know about anyone else, but I have *never* found this to be the case.
Dealing with a larger company you've got a far greater selection of people you can get to say "uh, yeah, I guess, why not? It's not really my department..." which you can take as a yes.
In a smaller company no matter what you're doing you've got to get it past Old Bob, who's been there since before most of the current management team were born and will argue over everything simply because he can.
