I feel like this is a good example of how difficult it is to find a good barcode scanner. It mentions permissions for contacts and full network access. I would have thought that those two permissions should not be necessary for a barcode scanner and point toward something dodgy going on.

It's actually not that difficult. F-Droid has a few offline scanners. It depends of course on how much of your experience you want automated. Though it would be nice if Android let you control the more granular permissions like network access.
