This appears to be just another opportunistic use of the court system to extract loose change from the deep pockets of big industry.
Of course those suffering actual damages should be compensated. But if feeling scared justifies payment then everyone else scared by anything and looking for a free ride should be paid also. By the time the settlement is all divided up, most of us will end up owing more than we're entitled to receive. The difference goes in the lawyers pockets!
