It seems to me, that the people who drive for Uber or let out their homes/apartments on AirBnB have no control over their destinies. If they are banned from the platform, their "business" is over.
What Uber and AirBnB have really achieved, is to replace management with an API: allocating work, evaluating performance, and firing people in automated fashion.
Those who utilize these platforms are something like contractors (though with less legal footing); not small business owners.
If this trend continues to the extreme, perhaps by 2050 most of the workforce will be managed by software. Imagine it, a nation of mechanical turks and task rabbits.
