You're absolutely right....except you're assuming there is an actual finding/admission of guilt.
The article speaks of a "settlement" being announced. To my eyes, the probability of that settlement including an admission of culpability approaches zero.
Infosys will not be blacklisted, they'll mind their manners and volume for a bit, then quietly pick up where they left off on the contract pile.
And....allowing for that tiny percentage sliver, what if they do admit guilt and are barred from government contracting for whatever period? They just slide the excess capacity over to the contractual pile of Walmart, Sears, etc.
As others have mentioned, $35MM, while not a drop in the bucket, is small enough to be absorbed as a carrying cost of doing business, given the revenue stream.
I hate the whole sordid "enterprise staffing" model that spawns this garbage and hope fervently never to work with it again.
