It seems sufficient to write off any trust you might have in that brand's name on account of the name only. That is, if Samsung's governance can't keep its employees or subsidiaries from lying with its name attached in the past, there's no reason to think they'd be able to do it in the future. This also incentivizes Samsung to police its underlings.

Of course, you might have other reasons to like Samsung's stuff (reviews, prior experience), and you might also be stuck trusting no one because all large companies have similar issues (so you're forced to buy from untrusted brands).
