True, though the situation isn't exactly equivalent.

Using another real estate analogy -

Imagine you bought a house from Fruit Builders company. The house came with a pool.

Now unlike every other pool in existence, this is a very special pool that just really cares about your privacy and security a lot.

It won't let you use any random pool toy (it has lasers), no it must be a well-behaved toy that is rigorously tested and officially notarized by Fruit company themselves (= non-employee contractors taking one look to make sure Fruit's cut is not being circumvented).

So you go to the supermarket, purchase a marked-up toy, the toy company reports its earning to Fruit, and Fruit takes their cut.

All for your safety of course.
