Raul, Do you have an equivalent phrase in Spanish for "You are making a mountain out of a mole hill"? If not, try "Tempest in a teapot". The discussion should have ended when the OP got his information. There is hardly any audio product you can name that is completely foolproof. In that adjective, the operative element is "fool". We all fool around with our stuff, and once in a while improper handling can adversely play into one or another idiosyncracy of any design.
If a child spills milk on your phonolinepreamp, and it blows up, do we blame the phonolinepreamp for not being waterproof?
Tonearms in particular are oddball devices, employing many different approaches to solving the same set of problems, and, while I would not bother to take a survey, I would wager that many, if not most, have an Achilles heel. Herb Papier, who designed the Triplanar, set for himself perhaps the most ambitious design goals of any tonearm designer of his era (no other tonearm allowed for adjustments in all planes, when the TP was introduced in the early 80s), and he met them all by taking some unorthodox approaches, from which we all benefit. Designers that came after Herb also benefit from having the TP to work from. (I am not arguing that the TP is THE BEST tonearm ever in the world; I am only saying that the TP was ground-breaking when it was introduced.)
