You say shamelessly but it could also be "cluelessly" (which doesn't excuse the company in any way). When I interview candidates, one of the questions I ask is if they know anything about licenses and if they can describe differences between for instance MIT and GPL. In my experience a surprisingly large number have no clue of the implications on a product and use code/libraries without considering the license. Either way, it's prudent to have someone review projects for this kind of liabilities before shipping anything.
