Why? The service is working as intended. He is able to store things on Google Drive. The issue is with the apps and the fact that he's trying to sync over 700GB via a 32-bit app. Additionally, they're offering him free storage. I understand that it's not ideal, but it's not like the service is down and he's unable to use it at all.
No I'm not. I'm merely pointing out why the app doesn't work. I don't expect the person using it to know that. I'm just arguing that the service itself works perfectly fine so his outrage about being a paying customer is misplaced and misguided. There are several solutions out there to sync with Google Drive. He's paying for the service, not for the syncing app. That is a free product that is available to anyone.
