As someone who hasn't played in a tournament for quite some time, but played in many in the past, I'll throw a few thoughts out there, somewhat at random.
-I live in the GMT-7 time zone (in western Canada). It has felt like that, for a long time, most/all of the tourneys I've looked up have been at times that are more convenient to Europeans. (This may or may not be true, but it is the perception I have; I have no data to back it up) This has led to me choosing between either staying up very late, which is fine sometimes, and I've certainly played in tourneys that started well past midnight locally, or choosing to sleep :p
-Wyand mentions real life getting in the way. In the last few years, I've had regular real life events that occupy my time Friday and Saturday nights most of the time (though with Covid social distancing, my Fridays are typically open these days) This means that a tourney that, say, five years ago I might have joined early evening, is now unplayable for me, so that the ones I have to choose are usually ones that start very late. This is certainly out of the control of the TOs, and we all have schedules that get busier or quieter over time, and it's not the same for everyone at any given time, but overall it should even out in terms of numbers.
-I have no real preference for speedbuilding vs slowbuilding, and most of the time, even the 'slowbuilding' ones I will typically spend less than 30 minutes on anyway, though when I was less experienced I would spend longer working on decks
-I still wouldn't mind the mark/nymph codes, but it gets much harder to care about anything like that when the game is probably going to disappear soon, or at the very least is never going to get an update again.
