Some recent hard data is the analysis of the #deleteUber campaign and market share in NYC of rideshare services. The data showed a dip that was swallowed (erased) by broad, gradual shifts within a few months. It was a recent front page HN story, but don't remember the title. I think it will take no more than a few million in a nationwide ad campaign running on TV to more than erase any #deleteFB campaign. That is, these campaigns cost the targets $$, but don't really fundamentally alter their trajectory (regulation could be a different story entirely).
The other thing in FB's favor here is how incredibly difficult it is for an average user to actually delete, vs. suspend, their FB account. I helped a non-techie friend with it recently and it took about 45 minutes. It wouldn't accept the user's password for deletion even though it worked to login. After 2-3 password changes, it finally worked.
(As most here know the actual account deletion page is hidden behind a barely visible link in ... a locked filing cabinet in the basement, guarded by a venomous snake...)
