Rustdesk looks good on the outside, but if you look inside, it has a really bad codebase and has done some sketchy stuff in the past.
Last year, it installed custom root certificates as trusted on windows, which is a huge security risk: https://github.com/rustdesk/rustdesk/discussions/6444
On linux systems, it forced its own autostart with no option to disable this behavior: https://github.com/rustdesk/rustdesk/issues/4863
In the past, when it didn’t have Wayland support yet, it edited your GDM config and just disabled wayland: https://github.com/rustdesk/rustdesk/blob/1.1.9/src/platform/linux.rs#L411-L422
Furthermore, the code quality is really bad. 90% of the linux platform-dependant code is just executing shell commands and parsing their output, while the same could be achieved in a safe way with proper rust builtins: https://github.com/rustdesk/rustdesk/blob/master/src/platform/linux.rs
While I agree that Rustdesk works pretty flawlessly, the codebase and the behavior of the developers made me distrust the software and I don’t recommend using it.
