Left hand, meet right hand
So, let me get this straight; LG have given out stickers with their own logo on telling people that their own products give you brain tumours. Aside from the diabolical scientific knowledge, doesn't this count as a pretty catastrophic marketing own-goal?
Son, let me tell you a story.
Back when I worked in one of LG's overseas branches, someone started leaking pictures of new handsets. As a response, management decided to enforce a new set of restrictions: from that point on nobody was allowed to enter the building carrying (I shit you not) "photographic cameras, video cameras, or memory devices".
Of course, no restriction was placed on personal cellphones – you know, those little gizmos that for years now have at a bare minimum included embedded cameras and internal storage? Not to mention that, since we worked in the mobile department, all developers had a drawer's worth of sample handsets in their desks, plus data-enabled SIM cards that were of course not audited in any meaningful way (and tended to be "disappeared" every now and again).
To top the cake, it was later found that the leaker worked not in our offices, but in one of the 3rd party companies that helped us test the handsets. Then again, all management wanted was to be seen as addressing the problem; they never meant their measures to make sense, let alone be effective.
"Face-losing pointless reactions to the wrong problem" could well be LG's internal motto. I can totally picture some executive coming up with the idea that what their handsets needed was something to reassure punters they are safe (because, you know, that's why they're buying Apple and Samsung in droves) and then delegated implementation to someone who couldn't read English, or cared to.
And you wonder why LG's livelihood depends on me-too phones sold in bulk to carriers?
