QQ is also playing with the input method?

QQ is really powerful. No matter what kind of things are useful, what can make money, and what is popular, they want to participate in all. Over ten years, QQ has become a hero in the Internet world. Google was founded in July 1998, and four months later, Tencent also came online. Now, one has become a giant in the search industry, and QQ is also an outstanding player in the IM field. Now, two big companies in different network fields have simultaneously released Chinese pinyin input methods, which is a good thing. After all, we have more choices in Chinese input, plus the previous Sogou Pinyin, pinyin input can be considered a trend. However, looking at several input methods, although they are not exactly the same, they are also very similar. Is there a problem of plagiarism inside? I don't know if anyone has studied it...
