Reputation only matters if it leads to a loss of sales. I’m sure ads don’t have enough impact to drastically lose more money than the ads otherwise make.
As long as they can make a reasonable argument, they’re good.
A legal requirement to maximize profits would be insane. Amazon couldn’t have spent a decade forgoing profits to build up R&D. Chipotle wouLd have to use cheaper chicken. Companies couldn’t donate to causes. It simply doesn’t work that way. (As someone else has pointed out elsewhere on this thread, the Supreme Court agrees.)
