In the evening, I watched "Whether SMTH, which originated from Tsinghua University, uses GPL rules in this way" was very touching. But think about it, most computer users in China don't even bother to protect the copyright and intellectual property rights of genuine software, let alone GPL rules. Perhaps, for some so-called copyright-conscious people, it is just a temporary rule of the game. Once you get tired of playing the game, keeping the rules will only hinder the expansion of your own interests. To put it bluntly, in their eyes, the GPL is only used to establish a cornerstone for obtaining profits, a condition that allows them to legitimately steal the fruits of other people's labor.
I don't know what smth is, but at least I won't use it in the future. Because I am afraid that I will touch their copyright consciousness in the future. Who knows one day, they will suddenly announce that smth's performance and development methods are excellent and are very precious things. They only want to use them themselves, and others have no right to use them. Then I can only stare.
The preamble of the GPL makes it very clear:
when we talk about free software, we mean freedom, not price. Our GNU General Public License guarantees that you have the freedom to distribute free software (and charge a fee for this service if you wish); guarantees that you receive the source program or can get it when you need it; guarantees that you You can modify the software or use parts of it in new free software; and make sure you know you can do these things.
To protect your rights, we need to make provisions that prohibit anyone from not recognizing your rights or asking you to give up those rights. These provisions translate into your responsibility if you modify the free software or distribute copies of the software. For example, if you distribute copies of such a program, whether for a fee or for free, you must give all rights you have to your recipients; you must ensure that they receive or have access to the source program; and you must give these terms to your recipients; They watch so that they know they have such rights.
