At first I was like "oh that's dope, they're sending it to all owners, not just providing them for new cars purchased after the announcement." Then I realized they kept saying "eligible owners" and nowhere does it specify what eligible means. So I will reserve judgement for now.
Handing out adapters for free is the best way for carmakers to handle this transition, so I'm glad at least 1 is doing this so far. Let's hope the others commit as well.
