How exactly is this going to stop scammers from simply modifying their scam runbook to say "Turn this thing on, and get back to me in 24 hours.", and then continue on from the next step?
We know from Nigerian email scams that these things can stretch out days, weeks, months, all to get the victim to do the thing.
The Nigerian type scams typically prey on greed; time pressure isn't part of the draw.
There's another class of scams where the draw is fear - "your son is in jail", "your bank account is under investigation and will be closed in 24 hours if you don't act now", &c. They rely on time pressure to prevent the victim from reaching out directly to the parties they're lying about and disproving the scam.
This is aimed at that particular type of scam and that particular type of victim.
but it seems govts arent interested or incapable of solving the causes (education, opportunity, destitution, etc etc) and probably also influx of scams from sanctioned countries (again a society/world level problem) that cant participate in the world trade etc...
so they lean on the technology companies to lockdown things more because what else can they do?
