No everyone can attend some of the conference and trainings due to location and other considerations. Through these make money to Q if the material is made accessible to all Q users there would be an increase of the quality of algos developed. Hence it might be worthwhile to release the videos of the conferences, seminars, meetup, trainings online. If they are paid perhaps they can be released after a lapse of time (say 3 months after the event). People who want to get the information fast or live interaction can continue to pay generating revenue to Q and also being generally accessible helps Q users also improve their algos.
