And if something like HN had existed at the time - commenters would be lambasting the protesters for how self-righteous and self-important they must feel; for using the workplace to inflict their personal morals on others; for not respecting IBM's right to make money (thus paying their hefty salaries) as it sees fit; for not respecting the rights of other workers at IBM who couldn't care less about the matter, and who after all are just trying to lead their best life, you know; how no hiring manager in their right mind could afford to have anyone involved in this sort of protest on their team, etc. And how few people will notice this petty attention-seeking outburst, and surely no one will remember anything of it in a few days time, anyway.
You can be very, very sure.
