It seems to me that a person is too politicized, openly hating the country in which he lives, provoking a certain type of people with attributes of faith, appeals and slogans in the pictures, has no right to call bastards of users of the service he recently headed. Just because for other people he can also be a bastard, for various reasons. This is how the world and people work. To insult others publicly, while they are customers of the service you have headed, is the last thing. After that, usually fired. Or cease to notice.
