I think it is offensive to accuse someone of astroturfing or being ‘an apologist’ simply based on being employed by a certain employer and expressing certain views. Even if one’s opinions generally support one’s employer – which I expect would often be the case in the socioeconomic class where people are able to choose their professions – that doesn’t mean they post deceptively or for hire.
In any case, Xeni’s point is key: that today’s security is different. That is written several times in the linked article but I admit I missed that detail too.
