People on the CS forum are very very fast to correct what they see as incorrect information. This was a case of Glindagon being technically correct, but also being really stubborn in not admitting that the GMs are also limited by policy - so it is also technically true that they can’t change guild leadership outside certain conditions.
One of the people they argued with set forth the conditions for those policy exceptions which are super limited.
When that was pointed out, Glindagon admitted that part was true, apologized, and a Blue locked the thread after commenting to confirm what those conditions were and that outside of that Blues don’t change guild leadership, even if the code does not stop them in a technical way.
