Lin Feng made money, but he wasn't happy. On this rainy day, he drove alone to Wutai Mountain, where he heard that one could resolve various unhappiness in life. When he was in college, he was already doing open source, having launched many projects over time and received many stars. At that time, Lin Feng was very happy; his joy came from each star and each thank you. He felt that he was helping others through his work. But this happiness didn't last long. A kind email shattered Lin Feng's open-source dream. The sender was a user who told Lin Feng that several groups had packaged his code and sold it as a SaaS, making a lot of money. He himself was a victim, having spent 19,800 to buy this SaaS service, and only after a long time did he realize that Lin Feng had an open-source project on GitHub, feeling cheated. So he emailed the author, hoping that the author would also protect his rights. Lin Feng opened their website and saw that they had sold over a thousand sets. Doing the math, he realized they had directly made tens of millions. Lin Feng sent an email, and their reply was: "Aren't you open source? Why do you care what we do with it?" From then on, Lin Feng archived all his open-source projects and withdrew from the open-source ecosystem. Not only that, in a fit of anger, he made all his open-source projects closed source, relying on his initial fame and traffic to continue making sales. "Actually, when I switched to closed source in the first month, I was still very happy. Because I had never made so much money before," Lin Feng said, looking at the overcast sky. "But starting from the second month, money no longer brought satisfaction. I couldn't find anything that made me happy. It used to be open source, and now it's gone." The abbot listened and said one sentence: "If you seek within yourself, you will see your true heart." Lin Feng didn't understand and asked the abbot, "Could you please explain this in detail?" The abbot said, "Your true heart is to help others, so why are you still entangled in whether this helping hand comes from your own hand? You are just occupied by personal desires, and those riches that do not belong to you have led you astray." After hearing this, Lin Feng was very unconvinced and retorted, "You are just speaking without understanding the pain. Why should the things I worked hard on become someone else's wedding dress? And I don't earn a penny from it." The abbot said, "Heaven and earth nurture all things, but do they ask for anything in return? At this moment, with every breath you take, have you paid any fees to heaven and earth?" Lin Feng asked, "The things I worked hard on became someone else's wedding dress, and they are still making money. I can't accept it." "Young man, when doing things, do not forget your original intention," the abbot said, brushing off his robes and leaving Lin Feng in the temple. Lin Feng reflected on the abbot's words and thought: Others using my open source indeed helped more people. I opened source to help others. Although I can make money now with closed source, the number of people I help has decreased. Isn't the greatest joy of open source the openness and co-creation? Perhaps it really is my jealousy that has caused this? Lin Feng walked out of the temple, and at that moment, the dark clouds outside began to disperse, with sunlight shining through the clouds onto the lotus leaves in the pond. ...
