These companies you mention, at least the tech ones, are all way more open to third parties interfacing with whatever products they have or data they produce.

They are more like big city gangsters willing to do business with whomever as long as you pay them protection money, while Apple's ecosystem is like a gated community where you get shot at the door if you even so much as look like you can't afford to get in.

Do you have any examples of that? Facebook and Google seems open more in the roach motel sense - they get your customer volume but continually adjust the terms so you get less of the ad revenue (pivot to video, ad words’ declining payout, the need to pay for placement in search or adopt proprietary tools like AMP not to be pushed down the page, etc.).
