Wasn't aware that a company had to officially acknowledge every time it changes minor internal policy/strategy/hiring or firing sales employees/IT-website alterations? News to me. Sure doesn't sound like a productive routine to me if they had to alert investors each and every time.
Infact I think it was a very bright and necessary idea to remove individual email addresses. Those should be kept internal like most businesses do. Only the vital contact info should be public. I don't for a second doubt they were getting bombed with pinkyland investor questions and possible spams from the likes of Defiremen and crew. It would greatly annoy me if I had to wade through those type emails while trying to conduct routine business and inter-departmental emails. Would you not agree?
I noticed you side-stepped my recommendation... so try this: why not send a professional concise email to the investor relations address with a header "Attention: Claude Lemay" followed by your questions? Or call them up and then report back what you find, instead of relying on pure assumption.
