"get them to agree" is one way to put it. If they want this our government can just show up with guns and force it to happen. The government already collects data from corporations (including apple according to snowden's leaks), sometimes taking over parts of a company's offices, installing hardware on the company's network, and filling those rooms with government employees in order to do it. https://en.wikipedia.org/wiki/Room_641A

It's not sticking your head in the sand to state that the entity which owns a device is free to install the software they want. The person operating that device does not own it and thus does not have the right to decide what software it runs.

Ignoring the long-standing norm of company-owned and provided devices using preinstalled software that the user has no control over for some sort of "gubmint bad" sentiment is really juvenile. This is how work-owned devices are and have been for decades.

Whether the white house app itself is good or bad, or the administration is good or bad is an entirely disjoint argument. Businesses which own the device and provide them to employees have the right to manage the software on the device they own. Do you really want to argue that the person who owns a device does not have the right to manage its software? Because I don't think that's the argument you want to make here.
