You, a 3rd party developer making custom software products for a mobile platform, are no longer allowed to have customers yourself.
Instead you must grovel and beg and pray that our lords Apple/Google consent to allow you to rent their customers.
This consent can be revoked at any time, you will pay through the nose for it (20%+ of total mobile revenue), and for basically all but the largest of customers - this consent is machine based and you will never be able to get a living person to so much as glance at any content you put into the process.

Fuck em both.
