Do the research on the cases in question. This wasn't publicly available information.
Information on Facebook can be restricted from public availability, or limited to friends only. The employers wanted those individuals' personal logins and passwords to peruse information on their accounts that wasn't
publicly available but only available to the account holder. You might think that's acceptable, several US jurisdictions don't. There are laws being passed to forbid it.
In the case of the device ID's none of that information is publicly available, unless there's a public database somewhere detailing all the numbers, names and addresses of the contacts on my phone, all the websites I visit, all the email accounts I use, where I bank, where I go in my car every day, where I spend my holidays?
