I don't know anything about the finance industry, but it seems to me that there are a number of industries where the non-compete term is irrelevant, as you can still become persona non grata. For example Companies B, C, and D know that if they hire someone from Company A, they will get sued. The merits are irrelevant if Company A can outspend them relative to the value of the prospective employee.
