It boils down to a simple problem of trying to fit facts to a preconceived theory, rather than basing a theory on the facts.
The longstanding beef is that there's two predetermined conclusions at work: that Samsung's phones must always emerge triumphant, and that Apple's phones must always fail. Facts are either exaggerated or conveniently omitted to support these views. Are Samsung's profits recovering in one quarter in spite of its phone sales, not because of them? Don't mention that last part -- surely the inevitable Samsung mobile monopoly is back on track! Did Apple have gangbuster early iPhone sales? Try to pick them apart to claim they don't count.
It's disingenuous, especially when many of us now know the underlying agenda and refuse to simply accept the claims at face value. It's fine to talk about Samsung's earnings... just present the facts plainly, whether they reflect well on your favorite brand or not.
I'm mostly surprised so many people still engage him in direct conversation. The topic itself unfortunately is valid, so I just try to comment around him.
Honestly, I feel like a lot of people actually like him posting nonsense b/c it let's them unload in righteous indignation at him and by extension Samsung.
Even accusations of him being Samsung PR are satisfying to many when the truth is more likely that he's some random fanboy. When the company releases clear breakdowns of revenue and profit by segment in a short period of time, it's utterly stupid for "PR" to try to spin an opposite story. The fact that his arguments are so bush league point to the opposite.
And what may be a surprise to many, I doubt he's even Korean as most nationals I know are not fans of Samsung, how much sway they have in the country, and how they treat their employees.
