> You will encounter business decisions you think are terrible but you still have to sell to your team.

This is incorrect. You don't have to. In fact, you shouldn't.

There can be situation in which stuff will need to happen regardless, yes, but that does not require lying and probably works even better when one does not lie.

Selling doesn't mean lying. It's usually possible to sell, or persuade, the team to move forward on terrible decisions, without resorting to lying, if you're a good manager.

Having said that, steering a team to execute on good or bad business decisions often do involve withholding information, and some argues -- though I disagree -- that's also lying. If you subscribe to that reasoning, then I suppose you would be right.
