Most large software companies are not the problem - they actually do use H1B the way it's intended, i.e. to supplement their work force when local talent is unavailable on short notice; and they offer equal pay for equal work. They also normally sponsor their H1B employees for green cards as soon as they're eligible, so we're not talking temp workers here, so much so as a skilled immigration stream.
(Disclosure: I was an H1B worker before, so this is based on personal and anecdotal experience.)
Places like Infosys and Tata are the problem. That's where H1B is milked for cheap labor, and where all those legal schemes to lower the salary as much as possible are heavily used. So far as I know, most workers that they hire do not get green cards, either.
Problem is, the latter group is responsible for most H1B applications.
