Zeev,
>these law firms rarely go after situations where they have no chance of recovering their cost.<
Their game is volume. It is quite apparent that the amount of time and resources that they have put into these cases is minimal at this point. They have some newbie cutting their teeth writing up novels. They only spend pocket change until the case goes to trial. Then the partners get involved. Even depositions don't cost them much, because they get low level staff to do them. But in this model they bank on a settlement with insurance companies instead. Trials are expensive.
This isn't to say it isn't a pain for Wave. It certainly is. But it is to say these attorneys are not brilliant. They quite obviously have not qualified these cases. We know this because the simple dimple easy to google facts are WRONG.
Upon what criteria were they qualified? Certainly not the criteria of the case that they state.
They may be successful. We don't know. We haven't seen their balance sheet. But... they they may be successful in negotiating with insurance firms.
I agree Zeev that the question remains, indeed, why at all.
