Today, when I was browsing Weibo, I saw Tao Jianhui, the founder of Taosi Data, sued a cheeky company on Weibo, and actually copied Taosi Data's PPT page by page to finance, the title, text, and icons are all lazy to change. In subsequent tweets, we can see that the company's product name is "SourceDB", and the company name is "Xi'an Soth Information Technology Co., Ltd.". Teacher Tao Jianhui said that our code is open source, and we are not afraid of copying!

At present, we found that the company's official website www.source-db.com can no longer be accessed normally, and the default page of IIS is displayed. It seems that it is very hasty to close the website.

The actual controller of the company is Li Jia and Liu Liang.
