Lawsuits look bad and cost way more than the loss of a device. Even if people are making fraudulent claims, Sammy will lose cause it's a Note 7 bomb...

So whether or not it is safe, they will do damage control and pull them all back. Make a new device and clear their name. Investor's like to see that, and that's where the real damage to Samsung happened already. Also if they force everyone to replace the N7 now, the S7 will be the logical answer plus the $100 credit to use a Samsung device. If they drag it out longer many people will try the new LG V20. So they will save a few mil right there alone by forcing it now vs later this month.
Just my 2 cents.
Also I'm disabling the update as well since I can't get a replacement for at least a week.
