Panic runs a cloud-hosted sync service that syncs your credentials and connection info between different instances of Transmit you may have.

No idea if that's what google is targeting here, but that is a cloud service, that presumably gets a copy of people's Google Drive OAuth keys if they use Google Drive with Transmit and the sync service.

That isn't a factor in Google's decision making. An app is an app as far as they're concerned, whether it's a local client or some sort of hosted service.
