I wrote like an essay length reply to this thread and am going to shorten slightly.
Me and korv debated about the whole community <=> sharing issue back when the original CAST encryption was forcibly being kept private. I made the argument back then that when you make it more of a hurdle for people to get into the conquer community, the community will go downhill and eventually evaporate.
Yes, there will be leachers and there will be people who have no desire to truly learn... but putting up barriers to stop those people only serves to also block out the people who you WANT in your community, the next generation of coders.
I knew ZERO programming when I started into conquer pservers... the reason I put in some effort and learned some basics was simply because I joined right around when COEmu-Nano was released. I knew soon after joining I could have gone and used Lotf 5017 but I also knew that using Nano meant I was running on a patch almost no one else was hosting... My work would actually account for something (as contrast to lotf where just about everything had a half working 'release' for it). That source gave me a framework to test my skills and see a true result from the effort I put in.
Same thing when I started learning about proxies and bots. There was Tannel's leaked proxy, the login, game, password and spell encryptions were all public... These all served as a framework to teach myself with.
Basically more hurdles = less new community members = shittier community over time.
The problem is, those with the information to share are stuck in this perpetual state of paranoia that someone might someday rival their market share and therefor refuse to allow anyone into their bubble of knowledge.
Spoiler alert... having more interested people with a basic understanding of proxies/bots and programming in the community means more people with the knowledge and skills to write Co_AI plugins... NOT more people who magically have the knowledge to build a competing bot service. If someone wanted to do that.... well they'd simply crack the encryption themselves (the least of their time/worries when related to writing the entire bot that could hope to compete with the paid features boasted by AI/Chrome)
