有人跟 Eric Meyer 提議，將 S5 的 license 從 CreativeCommons 改成 GPL：S5 Licensing。
這是因為有人跟 Eric Meyer 提到 Creative Commons 並不適合用在 Software (依據 CreativeCommons 的 FAQ)，所以應該去找 Open Source License 用比較適合，而 Eric Meyer 說他不太確定這個東西算不算是 Software：
The one license that seemed the closest fit is the Expat license. But even there, given the way it’s written, I come up against the question: is a confederation of markup, styles, and client-side code really “software”?
我看他現在很頭痛了 :p
