I dread the day I'll make claims like this, even figuratively.
Even at a most surface level reading, this would suggest something like their MAU (monthly active users) at least halving soon/already.
I'd be very surprised if it was trending down even, let alone at this! Forget hyperbole, this is an outright überbole.
By all means though, got any data?
Anecdotally, I suddenly had almost my entire friend group on matrix after that as well. I had campaigned for months but AV was the thing that got them to finally sign up.
