As I have been in the IT/security world for decades I am aware. Are you?You realize? What a condescending way to engage in a conversation.
Of course. That's why I'm personally against side-loading. However... if someone wants to roll the dice side-loading an app (assuming that side-loading capability somehow became mandated), they should be made aware of potential privacy/security risks and press an Acknowledge button before proceeding - as I posted earlier. And accept responsibility for any adverse consequences that may occur.
As I tried to point out the mere fact that the EU. may force companies to open interfaces to their hw/sw means that there is another way hackers could potentially affect you, whether or not you sideload.
I expect it is obvious to you that I do not want this.
