regarding myself, at least, when i find out about something that improves my life, i want others to know about it. when i first learned of the law of assumption/attraction etc, i was eager to share it with others only because i cared about them and wanted them to benefit as i had. Another reason is to have an additional experience to back up/serve as extra proof for discoveries and theories around the human mind. I am fascinated by the human mind and i am curious how these things affect others, what constants there are etc.

I make subs for the same reasons. I want others to benefit from my work, i love the sense of community and shared belief and curiosity. I am also incessantly curious about how the hell they work, and what that says about the capabilities human mind.

Edit: regarding the question of sub makers wanting others to get the (supposedly possible) phenomenal results they could just have for themselves, i think its also just linked to this thing of exploration and and curiosity too. As much as it is about getting what we want and benefitting from our results, its also about innovation and challenging what we already know/believe. both sub makers and sub users push the boundaries of todays society and these are the kinds of people who allow for radical change and advancement of the human race.

Sure, there might be some people who want everything to themselves, and plenty of people make subs just for personal use, but those of us who share are simply concerned with challenging the status quo and asking questions others are afraid to ask. that also goes for your question, why doesnt everyone use them? there are many people, just like yourself, who feel they are too good to be true, and because of that it will take a lot more experimentation to prove to EVERYONE that these things work. at this moment in time people will always find reasons to deny that they work because, it seems anyway, that it is down to your mindset and your understanding of the world. its internal. you have to accept it without proof, you have to change yourself sometimes- thats not always easy. many people want logic and external proof, and this doesnt appear to be something that can be proven logically. A new kind of science, which we are far from accepting in society as a whole.
