I way almost shocked when I first saw it, all democracies of the world, and human rights, forbid discriminating people by their political views, and some of those companies, if not all, are even public. I do not think such level of bias can be achieved by any kind of casualty, there must be some kind of selection or purge of employed people, which makes it a discrimination as wrong as racial or gender discrimination.<p>Hope to know your thought, as the weight of those companies in society is undeniable high, some of them impact directly society's culture.
