These are kids who use messenger/whatsapp etc. No they won't be bothered to even switch messenger. The goal isn't to shut down some criminal network it's to just make word of mouth spread in 10 minutes instead of 1 I reckon.
Those applications/protocols already exist to 'work around' authoritative regimes around the world. Only their usage will be re-purpose.
And many are not "kids", and even so, "kids" will also be able to use them since those alternative communication apps are packages to be used by non-tech-savvy people.
