It's not just an abstract "organization" - it's people that you've known as friends and teachers for years who lied to your face and in writing.
Now, maybe believing that everyone your know is lying to you by default keeps you from being "deluded and upset" - but it's no way to live, in my book.
I quite agree. In fact I fully agree.
However, I do understand. Imagine board meetings. What to say about certain topics is jointly agreed and thus the situation you describe. Not optimum but real, worldwide and considered normal.
Thus I conclude that either a) the subject of pr itself is not a complete or optimum subject as yet. It would have to be studied as a subject in itself and changed for these situations not to occur.
or b) That all people in the world so to speak should be made aware of that when it comes to historical record then the only place to look is in historical research done by those with no connection to the organization or opposing ones so to speak.
In other words I in a way lay the responsibility solely on the shoulders of historians themselves. They should be completely neutral, devoid of any allegiance or even belief that an organization should be giving detailed and correct data. That's not it's job. It's the job of the historian.
When the public knows this, when the companies know this, then there would be more harmony and less delusion. For the companies would feel relieved, knowing they were only expected to give a general outline and the public would be happy because they know they have a choice and what they are getting and from where.
Understanding what I say here as part b) I think is the correct answer for it leads to seeing what's hiidden in plain sight.
Even in life, be honest, when asking about something, anything, you don't expect an in depth account. No, you expect an outline good enough to give you an orientation.
You also know that if you want to know all the ins and outs then it is your responsibility to go to another place where you can find a specialized text on the subject and do an in depth study yourself.
We know this, it's normal and indeed natural.
Even those 'friends' of yours who lied believed in the same system you did so felt it as responsible to bear the not telling you the truth. Yes, they see it as a burden they have to carry, a responsibility.
The system is at fault. Belief in it is at fault. We all are at fault.
