Human nature has proven that you can't. You'll always have preference and it can break down to the stupidiest of reasons - such as color, mascot, and etc.
I've seen more damage come from members of a community who openly admit their affiliation than members who hide it. The ones who hide it and are bat-poop crazy are ignored to the point where they become someone's signature for a good laugh. The ones that disclose their affiliation are for some reason revered and defended by those that support that team even though there is no garauntee what they say is even remotely true (JFAMD/Rollo).
Would you rather have never known that Rollo was part of AEG or that JFAMD was an AMD employee?
I understand the term "Ignorance is bliss" and it is a happy place. But not a place I would want to be. "Knowledge is power" is where it is at.
Scenario: An engineer is working on a project at AMD. Proud of their work and proud to be a part of their company. They want their company to increase technologically, financially, have a better reputation (especially if this person worked on bulldozer), maybe even wants their stock options to be worth more.
He/she belongs to several online forums and always talks up AMD. Nobody on the forum knows that this person is an engineer, or PR director, manager, or mail room clerk at AMD. AMD's social media policy encourages it's employees to post in forums as long as they are transparent about it stating their affiliation. Now, when this engineer goes home, turns on his PC and enters the forums, he/she is still an employee of AMD. Still proud of their company, still want their company to increase technologically, financially, have a better reputation (especially if this person worked on bulldozer) and still wants their stock to be worth more.
Now consider how many thousands of employees work for AMD worldwide.
Even if 1/10th of 1% of these people post in forums, that is a ton of people that nobody knows about, and you could be talking with right now on a forum here or somewhere else.
I am not ok with this. You can be all you wish, but I prefer not to be in the dark. I do not want ignorance for the sake of bliss. I prefer to know who I am dealing with just as you know right now that you are speaking to a member of Nvidia focus group. And you know this because it if fully disclosed. And I don't even work for Nvidia. Actual Nvidia employees are absolutely NOT permitted to post in online forums and this is strictly enforced with sanctions. This, is exactly what AMD needs to do. Don't know why anyone would object to this either. At least without a good reason.
