This is really a difficult and complicated question to answer and I can’t speak for why other people maybe did or didn’t agree to the settlement.
But the lawyers used questionable tactics to get people to sign. They disclosed very little information about the settlement, they gave an artificially pressured time line to sign, and at least I was personally threatened that they would drop my case and nobody else was interested in taking the cases.
It’s always hard in life to be the relatively smaller guy.
