Having just seen Mandrill's "free forever!" tier turn into a $240/year minimum spend, color me a bit skeptical.
Free is for entertainment.

"free forever" -> $360/year in a matter of days. Not sure what they were thinking how this reflects on their brand.
Mandrill's free tier was "12k emails, free, forever". It didn't last forever. The use of "everything in our power" in this announcement makes it essentially meaningless.
