Most people don't have a problem with bad behavior if it's justified.
A good portion of my income goes to pay taxes, yet Amazon hardly pays anything comparatively. If they actually paid proportionate taxes maybe my tax rate wouldn't be so high. Getting a good deal through an error is only stealing back some value that was already stolen from me.
It's not the best justification, but I could come up with a dozen more. The play field is so drastically tilted towards the big players that almost everyone at some point feels like they were cheated by the system, and so people don't feel bad cheating the system.
