The one thing I really hate that I keep seeing is the "It was available to the public so it should be at least partially aimed aimed at the public".
Seriously, fuck that entitled nonsense right now.
Just because something is accessible by you doesn't mean it should be aimed at you. Because the alternative is that companies make these kind of talks offline only, or invite only, which just fucks over the people that can't travel to these events for whatever reason. "Disabled, start-up, quarantined? Nah, fuck you. If you really cared about this presentation you would be here."
Seriously, stop that line of thought right now, it's toxic as hell.
Firstly, the only toxic thing I'm seeing is your aggressive attitude.
Secondly, every (most?) GDC talks are made public eventually. Like I and others have been saying context matters. This was the first time sony has talked about the ps5 in earnest so of course people are going to show up expecting to see SOMETHING. Microsoft understood this, sony didnt. It's ok to give sony a little flack for it. Marketing does matter and right now microsoft is running circles around sony.
