I don't think I'll ever get to request it, because I'm pretty sure it's going to fail, especially with my parents and other from this age group - having them download another app, signup, etc. will be too complicated.
My family group is all iphone users, so I thought about moving this to iMessage, which feels more possible, but again, I'm not even sure my parents understand the difference between whatsapp and iMessage, as they send me messages on both platform without much logic.
Like everything else "bad" that happens to Facebook, this event won't change much and impact on whatsapp will, unfortunately, not change anything.
Remember when corporates stopped advertising on Facebook? They're all back.
