Except when it becomes a reputational problem for the OEM: Excel sucks at X (i.e., don't use it for that) and Excel sucks can become equivalent in many people's minds.
Sometimes it is actually a problem of people 'holding it wrong' (as the meme/trope goes). And who gets the blame?
I'd say, the reasonable person test, if the mistake sounds like one a reasonable person would make, then fine.
I guess sadly the press will gloss over all the intricacies for a few clicks.
I also feel that dumbing things down probably just exacerbates this problem as "reasonable folk" have no clue how you actually get from a to b.
