Can Jialichuang open source things be copied and sold?

Kerry creates open source things that cannot be copied. Jialichuang's open source products can't be sold if they are copied, because open source means publicly making materials and drawings, and everyone can copy them. However, in order to protect the author's rights, some open source projects will restrict commercial use, which is equivalent to maintaining patents through public opinion. Even if the content is made public, it will be accused of selling the relevant results privately. When the amount is enough, you can even defend your rights through legal means.
