Seems like Google isn't leveraging their own tools properly then.

They can make a non-corporate device have a work profile with Google Apps Device Policy, and only that profile will be purged if the device is wiped by a Google Admin.

Even simpler for corps as large as Google is simply having a supply of contractor devices they completely wipe upon the termination of the contract. That's what my last company did.

They didn't require contractors to bring their own computers and phones to the office if they were needed for their work.

I'm sure Google could afford that as well as to manage it...

Google does do that. Lot of misinformation in this thread.
