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.
Probably something you'd notice more in the number of concurrent users each solution could handle per web server instance. Rust theoretically would let you serve more users with less resources.
I have listened since the time it was the Engadget podcast, then This Is My Next, then the Vergecast. Yes, it's fluff and not deep technical info, but it's really useful for keeping up with the overall zeitgeist of the tech industry. Also it's often funny. It's a nice, refreshing thing to listen to while making coffee on a Friday.
I preordered in Canada. Vancouver, specifically.
