Framework7 derived from onsen ui?

I’ve been researching mobile front-ends and I came across onsen ui (https://onsen.io/) which has been around since 2013.

The onsenui website bears a remarkable resemblance to framework7.io. In fact, it looks like framework7.io was copied from onsen.io.

My question is: was Framework7 derived from onsen ui? And if so, are upgrades and fixes to onsen ui being merged into Framework7?

They are totally different and has nothing common
