I think what you're seeing is frustration of a small minority of pilots who had some sort of fantasy that new rest/duty time rules would result in thousands of pilots being hired by the majors and the regionals.

Not only was this unlikely to happen, the purpose of these rules changes is safety, not featherbedding. If anything, rule changes that forced massive hiring to support existing routes would probably cause a reduction in flying, not an increase in hiring. There's no money in the till.
