Earlier quoted context omitted.
I agree that my comment was not constructive, frustration got the better of me, I will work on that. You might want to look into your abrasive/patronizing tone used to deliver that message. Also, I don't agree that comparing Gmail to cancer is minimizing the seriousness of cancer, maybe you are just not seeing the damage to email as a decentralized platform Gmail is doing.
Bold assumption of you, assuming a "patronizing tone" and what I am or aren't seeing -- by that logic, it would seem you "are just not seeing the damage cancer does" given your ridiculous comparison. Would you cry the same if Hotmail were the predominant platform? Regardless of that, it still wasn't constructive, and your "you might want to x" and "you're not seeing y" comments are much more patronizing than anything…
I am not "crying", but I would be pissed of as well if Hotmail or anybody else was doing the same. This is not about being a predominant platform, but about hurting legitimate email senders to "combat spam" in a way where using their platform, or one of the big players, is the "safest" way to get your emails delivered in a timely manner and land in the recipients Inbox.
