I imagine you're getting downvotes because of your smug hyperbole, but in essence, I wouldn't deny that that is a legit question (not the entire fontgame, I guess, but a core part of it anyway).

It's also one of the reasons to reduce use of proprietary software to a minimum. Especially, if it's a core component of the system. Flatline, it's an increased security risk you can't verify.

On a serious note: Are there legit reasons to have it being a core component?
