What you're ignoring is that 99% of our employees don't have the ability to cease doing business with these holier than thou assholes. They're forced to get these emails they don't want and they all spent time being being mad, annoyed, confused or upset, many spent hours crafting internal emails and following the very public discussion, many were annoyed by the eventual decision to stick with them. Many still bring this up when related issues arise. It's a collective waste of time and it isn't ok.
Would you be happy about a company that sent religious recruitment emails to all your employees?
Would you be happy about a company that distracted over half your employees for the better part of a day in some cases for no fucking reason other than to push their own personal agenda?
