Well that's helpful (sarcasm). Care to provide a reason why?

The key difference (in this situation) between GPLv2 and GPLv3 is the dyanamic-linker aspects. That is why per GPLv2, Wix only has to share the WordPress for Android-sourced GPL code, and any changes they may have made (if any).

Had GPLv3 been employed, Wix would have to also share any code that is dynamically-linked with the WordPress for Android-sourced code, which could include the entire app (minus graphical assets - something Matt learned the hard way).
