Google Play Services meets all the definitions of spyware. It's built to collect data on your usage and track your location and report it to a third party for their own interests. It's nearly impossible to fully remove, and it has replaced critical parts of core applications so you can't remove it without crippling your own ability to use the device.
I get that you're a fan, but it's impossible to define it any other way.
And as always, remember that any data Google can collect, the government can collect through them. They have no legal ability to resist those requests. So, your precise location history at all times? Yeah, that's an open book.
