The primary difference between a logged-in user and one who is not logged is the absence of any contractual agreement that legally binds the anonymous user to terms assigned by Google.

I haven’t read a Google EULA in some time, but as I recall it was long and full of rights and waivers and privileges and protections you assign Google in regard to anything wherein you might possibly have legal standing. The log-in request is not universal, nor is it random, so it’s safe to assume as a hypothetical that for whatever reason, Google wants that in this specific scenario, in this specific geographical region.

On the other hand, if you’re not signed in – AND Google can’t link your anonymous use to an actual agreement you have with them elsewhere – Google just doesn’t have that same comfortably protected legal situation. (See Disney’s recent legal behavior for an example of why, if Google can still link your non-signed-in behavior to an existing EULA elsewhere in their walled garden, you may still be fucked.)

OP’s map seems to be located in the EU, which makes a legal difference as well. We already know that Google does whatever the fuck Google wants in the US, but in the EU laws tend to have more teeth as well as legislators very willing to go after violators.

All that said, I am not an attorney in Spain and I damn sure don’t work for Google, so don’t come at me lol.
