Nobody is forcing you to do these courses, so why are you so concerned. They were probably written by instructors looking to expand their teaching abilities and make a living.I mean Dive Against Debris Diver and Shark Conservation Diver. Come On!!!!
Just get out there and dive. Once you've logged more than 24 dives and have a bit more experience in various conditions then perhaps you can involve yourself with more pertinent courses that suit your diving.
