There is an 'I hate Kroger' facebook page. There should be one for Garmin.
I have found this web page eases my revulsion for Garbge Express + Connect

antfs-cli --pair simply gets the .fit files to disk. I use fit2tcx to
make the ascii .tcx files from the .fit files.
Yes, this does not really speak to windows users, but maybe with hue
and cry this software will emerge under windows.
The very idea that you cannot copy your .fit files to disk without
reporting to the mother ship (Garbage Connect) strikes me as unethical.
