The issue is not that you expressed your opinion, it's the way it was expressed. An accusatory tone of shady business practices will not go over well, especially if you've been following the release of this product from the beginning like a lot of us have. If his product was sending data about you or your device somewhere or caused pop-ups on your emails I would understand your anger. I see advertisments at the end of emails from Yahoo, Hotmail, and AOL that for all I know you can't turn off.

The final product was shaped from users giving Ani their opinions. I hope you try it again (with the attachment turned off) and let him know what you think should be made better. I know he'll listen.
