"If I have a wandering monster table with 1 encounter and a 100% chance of that encounter - how is that different then the quantum ogre?"
Cute. Well, the original article postulated 3 options (groves of trees), and a DM that no matter what the party did, found the ogre in the first one, and the mcguffin in the last one the party entered. And there was nothing they could do to change or avoid the outcome.
This strawman assumes that all improvisation on the part of the Dungeon Master is negative. Clearly there are appropriate times to do all of the things that I recommend against doing. Older editions even contained rules to bypass the need to do them! A classic example is morale. In Pathfinder, if the party has clearly won the fight, and there are just a few orcs left, having a player kill one instead of leaving it with one hit point is a perfectly acceptable time to fudge the dice, because the outcome doesn't matter. All you are doing is facilitating interesting choices, instead of uninteresting ones. In earlier editions they would have already fled due to morale failure.
You will spring an encounter on the PC's You will roll sometimes and ignore it. You will dictate player actions. Just always be sure to do so in a way that maintains agency.
