Certain aspects of Sanchin-ryu are trade marked, such as the logo and certain corporate items as part of their NON-PROFIT organization/status. You can NOT trademark punches/kicks or form/kata names. As far as I know, there are 3 different styles of Sanchin-ryu. The current one we are discussing, then there is one that was founded in England. Also, at one time there was someone in New York that was claiming to be the founder of Sanchin-Ryu.
As to CGM Dearman's history. Yes, he was an orphan and spent alot of time in various group homes/foster homes. He grew up in the south and would go to the nearest dojos to where he was staying and would trade lessons for cleaning the dojos. He started in Judo when he was around 6 yrs old and also studied boxing when younger. He was drawn to the martial arts, partly due to the training and partly due to the fact that he had adults that cared about him and gave him attention. Many of the places he studied didn't advertise what style, it was "Jim's Karate" or something similiar. The last style that he studied was Isshin-Ryu and he was a 3rd Dan. Sanchin-Ryu is heavily influenced by Okinawan styles and Isshin-Ryu in particular. Whether you agree with it or not, CGM Dearman has chosen to have students focus on Sanchin-Ryu itself and how it can improve their life and not on himself and what he can do or has done.
When Sanchin-Ryu was first declared as a style in 1978, CGM Dearman used to do public demonstrations and would do (as he calls them) tricks to get interest. He would do sanchin and let people break 2x4's over him. He could take a piece of 1/2 in. rebar and bend it. He would also jump up and kick a basketball hoop. But, to him this is not the essence of what true martial arts is and once Sanchin-ryu started to grow stopped doing demos like that.
Our Sanchin form, is very similiar to Goju-Ryu's Sanchin Dai Ichi and Isshin-ryu's sanchin kata. It emphasizes the dynamic tension and abdominal breathing with alot of closed fists, as opposed to Uechi-ryu's open handed and less tension.
Sanchin-ryu's main focus is on protecting yourself in everyday life. Most of the confrontations we get into are with coworkers, family, friends etc. and we need tools to help us with those things. Sanchin=3 battles, so all of our forms teach us a physical concept that we can use to protect us, but it also teaches us a mental strategy of how to apply that into our everyday life to diffuse verbal situations. Fighting is easy, you can take a very small amount of techniques to train to be able to protect yourself (your bread and butter so to speak). But, an MA should have more to offer someone than just punches, kicks, etc. All of our certified instructors are trained in the Project Secure Child (PSC) which goes into strategies of dealing with a bully (cyber, physical, verbal), how to deal with peer pressure, stranger danger and other topics that are addressed each week in class.
As to them "selling their style". CGM Dearman is very passionate about what he does and helping other people. CGM Dearman will also tell you there are many paths to get to the same mountain top, he thinks all styles have merit and worth so he is not out to convince someone that this is the best thing out there. As long as you commit to something and are being helped by it more power to you. Sanchin Systems is and always has been run as a non-profit organization. CGM Dearmans's annual salary from it is $1 a year because that is what is required by law. He does not take money from that, he earns it in other ways (such as giving lectures, etc.).
In the end, it's like my old roommate used to say. "Everyone sucks to someone else". There are people who didn't find what they were looking for in Sanchin-ryu and left to go elsewhere and there are people who studied other traditional styles that started with Sanchin-ryu and love it. Remember all styles are artificial and are only one person's view on what fighting and combat is. Find what fits you the best and stick with it, but I do NOT agree with the tendency for people to have to insult what is different than what they do to try and convince themselves that they are bette.
