That might have been true in the past, but nowadays at least macOS/Android/iOS can enforce several restrictions on the apps you install, like prevent them from changing OS settings/files, limit access to only specified/opt-in directories, limit the amount of background activity, etc.

I don't know about Windows or Linux though.

Windows applications can easily install TLS root certificates, which essentially all „anti virus“ tools (i.e. snake oil) do. On Linux, it’s obvious; if you’re installing something as root, you can add certificates. In that context, apple is doing something right and makes it rather tedious to install root certs
