Yes, I have worked free for charity, free for friends, and free/speculatively for or with people on projects hoping that some pay off. Some do. I have a SaaS product with a free tier (like Mailgun) and I have had an app/game which was free with an upgrade. (My initial point was not about the freemium model but about other changes that have made working with Mailgun difficult.)
