This particular account was created because it was a throwaway to respond to a post regarding working conditions at AWS, hence the name. I am not shy about the fact that I work at AWS, and if you read my comment history you'll find that I think it's a garbage company that I am currently trying to leave, and I support unionization of workers.
But none of that actually addresses the question that was asked of you. Where are you getting your information that "They can't ban some and allow some, which is what happened here."? Because that information is not in the article, and it seems like you're just making it up. If there is such information available somewhere else, I'd like to read about it.
If you have an actual answer to the question at hand rather than trying to avoid the question and make dumbass assumptions based on my username, please do respond. Otherwise, I'll just assume that you are resorting to ad hominem attacks because you don't actually have any facts to back you up.
