Come on, I installed Manjaro DDE just yesterday and it is very good. I don't realize issues, and it not come to me too big issues. Of course, I don't know processes of maintaining but as a end user Manjaro DDE is looking very good.
Anyway, I am not programmer, I am a social scientist, I don't know and I can't understand what exactly is going on. But It looks to me this is likely corollary of trade war. Because Deepin team just wrote their planning and even we didn't saw what they did, right? And as far as I know it will be open source, and we will see what they are doing. If they produce closed codes, we can think again about situation. Therefore it is just prejudice for me. And this sentence will be politic but it is true, firstly USA must stop spying to people. Apple, Facebook, Google all of them spying us better and longer time than any Chinese company. Anyway, this is true we are using Linux because of these issue, this situation is important to us therefore previous argument can be meaningless. But these are becoming because of our perception. We are doing just prejudge about Chinese company or society.
In the second part of subject about problems of DDE: Gnome also have a lot of problem. For example desktop icons in Ubuntu, it is very funny. In 2019, you can't drop down any icons directly desktop, and they can't resolve this problem . As far as I know DDE is younger than Gnome and KDE. Problems could be normal. But their desktop environment is just beautiful. And I can bear DDE problems more than Gnome problems because it is more beautiful and there are no performance difference. But in this subject, for me it is decision of maintainer. Because maintainer working on these problems as a voluntarily. And if maintainer says I am bored and I just quiting, it is okay for me.
And lastly, Deepin gave us a really beautiful desktops, end of dozen years. Because of this thanks to them. And also I want say thank you to who bring this beautiful desktop to beautiful system such as Manjaro.
And of course all were my personnel opinions, I am not expert in these subjects, if I have written something wrong I am sorry.
