Both are extremely valuable. Giphy data would include a wider user-base, but Onavo has much deeper data (all of someone's mobile data traffic, which would include seeing what someone is searching on Giphy and in which app)

So we should expect TikTok to either replace or phase out giphy right? I mean the historical analytics would still be good for a while but....

Giphy wouldn't be banned on the App Store, though.
