One aspect of "picking your battles" is choosing battles that are win-able. The case against Advertising ID is much easier to make than location tracking. Advertising ID can fall under the scope of ePD (ePrivacy Directive), not just GDPR, and the ePD is more strict and does not have the same allowance for balancing competing interests. Schrems is definitely strategic about the battles that he fights. He's been waging this war for close to a decade now. He puts a value on precedent, and will take on more clear-cut-but-lower-stakes cases to help build case law towards the higher-stakes cases later.
