Hi, GANTTophant support here.
#1 As you copied corretly: "See, edit, create, and delete YOUR SPREADSHEETS in Google Drive". The permissions did not include all Drive documents, only spreadsheet documents.
#2 We took your comment seriously and thought about these permissions. We downgraded it to "View and manage spreadsheets that this application has been installed in", these are the minimum permissions that the addon needs.
There is no "big and bad data collecting corporation" in the background of this addon, it is a fun project which is maintained in the free time ;-) Maybe you can rethink your review?
