Mistakes are human, sure. But companies love to put labels on things like this with seemingly little thought. Offering something for free with the 'forever' label on it is I believe deliberate - trying to distance themselves from others who have offered a free plan, but either pulled the rug once they got popular, or snuck in conditions or time limits. If they had withdrawn the free plan from new customers, but grandfathered in existing users they would have kept their promise and earned at least some good-will.
