I mean, do I need to?
There has been a clear and consistent pattern of the DM needs to be given massive leeway--essentially unlimited trust--up until the point they've gone so egregious you can just write them off as a jerk, at which point everyone just says "don't play with jerks".
There has not, as far as I can tell, ever been an example of someone taking seriously the idea that there are states between these points. Every time I bring it up, it gets outright dismissed with "don't play with jerks" or various variations thereof--as though the only possible problem is inherently bad people ("jerks"), and everyone else will never be a problem so just trust them for goodness' sake!!!
Yes, you do need to, because nobody that I have seen has even come remotely close to saying that. I've seen the following.
1) If you can't trust the DM, you shouldn't play in that game. This does not say anything about massive leeway or unlimited trust. Not even close.
2) Trust should be extended to the DM when you start play. This does not say anything about massive leeway or unlimited trust. Not even close. It does mean that you should not assume incompetence or malice on the part of the DM. It also means that if you see something that might break trust if true, you should talk to the DM about it, probably after/outside the game if it's something that will take longer than a minute or two.
3) The player can and should talk to the DM if he has issues. He just shouldn't disrupt the game for everyone, so if it can't be resolved in a minute or two, leave it for after/outside the game. This does not say anything about massive leeway or unlimited trust. Not even close.
4) I've seen it said that the player shouldn't be a jerk. The context of that is disrupting the game and ruining the fun for everyone else at the table. It takes no massive leeway or unlimited trust to not be a jerk and disrupt the game. It also isn't talking about players who bring up something minor that would take a minute or two in game.
5) It has also been said that if the group or a majority of it has an issue, that it's okay to stop the game for a lengthy time to discuss the issue. That, just like all the rest, does not say anything about massive leeway or unlimited trust. Not even close. As an aside, in my experience the overwhelming majority of the time if it's something that bothers the group, the group tends to talk about it with me before or after the game, not in the middle. But that's just my experience.
So yes, if you have seen someone saying that the DM can do no wrong unless he's outright villainous, you need to link it. Because I've only seen it said by people misrepresenting what those on my side of this issue have been saying, not by anyone on my side of the issue.
