People have taken this to a ridiculous level. Giving practical advice about how to avoid problems is not blaming the victim. Telling my child to look both ways before crossing the street is not blaming him if he gets hit. It's not wanting to see him get hurt when the person actually at fault fucks up. Telling someone to avoid non-ASCII characters because a program can't handle it is not blaming them....
Your comment was unhelpful. Great! Not their fault! What now? It's also part of a larger trend that will lead to people being hurt.
