Not really sure what you mean 😕
You proposed that the Trump admin not engaging in press briefings and the Biden admin embracing daily press briefings somehow illustrates a meaningful lack of, or abundance of, transparency.
I'm arguing that Biden has objectively been the least available/public POTUS in modern history (backed up by concrete statistics). BECAUSE his administration has been actively hiding his physical and mental degradation.
That's not hyperbole, it's a direct rebuttal of your original point.
Press Secretaries flipping through and reading back prewritten propaganda to a room of "journalists" isn't transparency.
