There is no free market and there can't be - it's a theoretical ideal whose actual implementation is impossible, and we can only get so close to it without starting to incur extreme humanitarian costs. But since we can speculate about the outcome of a truly free market, here's my view:

In a free market, the first entrepreneur to get a loan from the bank to build up some of the infrastructure would beat all the public collectives - they could just build up, sell at a loss until the local collective gives up, and jack up prices as most users switch to their offering. Rinse and repeat, and with every iteration it only gets easier - because wealth and power compound, much like interest in the bank.

A free market structurally favors larger companies. Unlike what some people say, government intervention is neither necessary nor sufficient to enable monopolies - all that's required is the positive feedback loop on capital. The more you have, the easier it is to get more.
