Criticism of Apple products is fine.
Apple bashing, i.e groundless and blatantly incorrect criticism of Apple products is not.
There is a difference.
There are a number of people here on PPRuNe who take much delight in simply bashing Apple because its the fashionable thing to do.
Of course, I would rather you don't bother criticising other products (irrespective of manaufacturer) and just get on with using the product you personally prefer .... but even that seems to be too much of an ask for some poeple !
