Ok, it sound actually to me like your experiences might not e contradicting, merely that you talk about somewhat different phenomena.
First off - I have actually met the mythic GM Tyrant. I was my friend. I think we were about 13 at the time, and he was running his first game ever. He ran the first part of a module fine. Then he put us in a ship to ship combat with the opposing ship having an endless stream of enemies, and a conspicuously increasing number of balistas as we managed to fight trough the horde he was sure would TPK us. He later admitted doing so anticipating the arrival of a module he rather wanted to run/play. Rather prematurely though, as said module never arrived.
With this out of my system, it appear
@Thomas Shey has a lower threshold for the phenomenom observed. It appear we are rather talking about games where the GM has a more authoritative style than the players would prefer.
I am as such curious what
@Thomas Shey makes of the following anecdote. When I was peak integrated in the local RPG community the best known and revered GM in the city (possibly in the country) was an individual that provided incredibly imaginative experiences delivered in an extremely professional and engaging maner. He made Matt Mercer look like an amateur in terms of delivey, and I am serious about that. He was also by far the most overtly top down authoritative GM I have ever experienced, and he would not be shy about promoting this as a central part of his "method".
Here we have an extremely well liked GM who's popularity is in part
because of not
despite a very strong top down approach. How does that fit into the model? My take is that there are certain role models that actually manage to make such an approach work, but that there is a underforest of imitators that try to acheive the same thing, but just don't have what it takes to make it work.
I am in absolutely no doubt that there are lots of groups out there with a GM that is overdoing the authority thing compared with their own skill and player preference. I think this is valuable to increase consciousness about. But I do not think it is correct or constructive to look at the authoritative style of play in itself as a problem. I think it is a hard style of play to master, with many pitfalls. But I have been privileged enough to get to experience first hand what magic it can produce when actually competently wielded.
