An article attracts discussion is good? sure. I did not know about trak.io, now I do. The attitude in the article towards "freeloaders"? not so good. I won't argue whether it is better or not to have a freemium for "your" company. But commitment should not be broken so nonchalantly. Did you at least grandfather beta customers to a free plan? If not, you did a bait and switch, and that does not make me wanna do business with you (and I would have become a paying customer).
