Your FastAI criticism isn't really accurate, as FastAI is free online courseware. I suppose you could claim that jhoward makes his living from his personal brand, and FastAI helps that... but that's a bit of a stretch. It would be much more valid if they were a business, rather than an open source software and free course solution. Even as a competitor, it's probably useful criticism to get a negative perspective from a competitor.
