It seems they were trying to hide the app being Chinese, added a trusted certificate on your machine without prompting, complaints about not really being open source, etc. It doesn't look very good to me at this point.
Search around a bit and you will find these issues being raised by people, at the same time the answers fron the team seem very dismissive and amount to "please no politics here".
Check the wikipedia page edits as well, weird stuff. I don't like weird stuff when choosing a remote control software.
Rather paying Anydesk than using this. At this point at least.
Edit: to add, rustdesk was using and sending data to a chinese server for some reason. At least they got an EU one instead, at least according to wikipedia, but that could just resend whatever data forward. This is all just what I see on the net though. But, enough for me to choose something else.
