>> I don't see how you can have an independent business and be entirely dependent on third party for your operations

Like a lumber mill that buys logs from a logging company? Who subcontracts to individual fallers? Who buy their chainsaws from a chainsaw company, their fuel from a petrochemical company? No business isn't entirely dependent on third parties. That's what it means to exist in a healthy economy.

A "farm-to-table" megacorp that owns everything from the source of every raw material through to the finished product is a nightmare, an entity that needs to be reigned in and broken up. Capitalism is a competitive game, but a game that can never be allowed to end.

But what about the digital economy? It's interesting that the length of the supply chain for digital goods and knowledge work is nothing like physical goods. Google, Microsoft, and Apple are end to end, don't have to depend on any other software company if they don't want to (until LLMs, anyway, except Google).

The difference is that the lumber mill isn't giving the logging company all the information required to run a lumber mill and the logging company isn't turning around and selling said information to anyone for $200/mo.
