I don’t buy this excuse. Just make it “opt”, meaning neither option is the default. You have to choose “Yes, contribute diagnostic and bug data to Fedora (recommended)” or “No, keep my data private” before you can continue. Put a big “more info” link to documentation on what is collected, when, and who gets it, and how it’s used.
It somewhat under-represents those who value privacy most and over-represents those who want to help Fedora with their usage data, but I argue that’s a good thing.
