God why are people here so obsessed with optional telemetry. Fedora aren't selling your secrets to advertiser's, they are just trying to create a better experience for users, and you can always opt out.
Has it ever occured to you that it is also good to give back to the open source community?
"It has a cool default theme for Gnome, and there's a colored bash prompt."
The "cool default theme" in Fedora is the default Gnome theme. There isn't a "colored bash prompt." Fedora is a major distribution on par with stuff like Arch and Debian, so news about Fedora is news about linux.
Love Fedora, hate Fedora, I couldn't care less. But at least do a little research.
Do you just look for things to get mad at? This hasn't even been implemented yet. Even if it had, it would be opt-in. And even if you opt-in, the data is all anonymous and you would be able to see exactly the data that gets sent out. If Fedora or anyone else really wanted to spy on you, I assure you they wouldn't let you know beforehand.
