Okay, but could you give me some examples? How is Android or iOS more secure than Linux or Qubes?
Access control is also more advanced, e.g. apps need to request permissions to the user. Not saying that desktop OSes are not making progress, but they are behind.
I don't know if Qubes qualifies here. Qubes runs Linux instances in VMs to compartmentalise them, but then each Linux instance has the Linux security model.
