I think it's worth reflecting on the fact that you took time out of your happy life to leave your original comment, which declared that you will use whatever small amount of professional power you have to enforce your personal grudge against a small set of companies you hate by refusing to hire their former workers.

Edit: Just realized you've left like 20 comments on this thread that are all grinding the same axe.

There’s an art to conveying a position on a topic without alienating one’s audience.
