It's an interesting question @FrogReaver. If you start from the position that the DM is interpreting things correctly - that invoking the background only allows for the long rest, is it still a Mother May I situation.
But, here's the thing. Even if the DM is 100% in the right, the player is still unhappy. The player isn't really unhappy about the interpretation of the rules, but rather, how that interpretation was used in the game which resulted in a situation that wasn't fun for the player.
So, in my mind anyway, it really doesn't matter who is right. The issue is that there is a problem at the table. Who's correctly interpreting the rules doesn't change that.
I guess what I'm trying to say is that MMI is the symptom of a problem at the table, not the problem itself. The problem is that the DM ignored the players unstated but pretty clear goals in order to use his own. The players wanted to be able to hide from the bad guys and then formulate some sort of strategy to move forward. The DM took that away and forced the players into a reactive rather than active role. The players couldn't avoid the encounter, couldn't plan for the encounter. They could only react to the encounter. The DM's choices deprotagonized the players. It took away their choices.
And, note, it wasn't the player's choices that resulted in this scenario either. If the players chose to enter the bad guy's stronghold and get caught in a trap, well, that's on the players. The players in this case though, have pretty strongly signaled that they want to be in the driver's seat and the DM completely ignored that.
