The restrictions on GPS prevent ballistic missiles, not MANPADs. Typical limits are 515 m/s and 18,000 meters (try using your phone's GPS on a commercial flight, it works fine near a window). Update rate is probably the biggest issue with GPS and MANPADs.

The headline is a bit sensational considering all we know from the reporting is that he isn't working there anymore. Fired likely, sure, but not for a fact.

My phone can regularly pick these up with a clear western view in Los Angeles. They're relatively low in the sky so they don't serve their intended purpose here, but I'm not complaining about having more satellites to lock on to.

Large fleet operators tend to self insure rather than having traditional auto insurance for what it's worth.

If you have a large fleet, say getting in 5-10 accidents a year, you can't buy a policy that's going to consistently pay out more than the premium, at least not one that the insurance company will be willing to renew. So economically it makes sense to set that money aside and pay out directly, perhaps covering disastrous losses with some kind of policy.
