I would have said that too based on our RT-AC68U right up until I read this post and thought "time to update that router" and when I did so, for the first time in many updates I was presented with a license agreement allowing ASUS to send basically every bit of data to a 3rd party (Trend Micro) for features I didn't ask for. I should have captured it but the data they described was basically every bit of data you can imagine not wanting to share with a 3rd party. I had to agree to get into the router management portal and at least they had a way to withdraw that agreement (which also turns off those features).
I can't believe ASUS even considered this idea in this era of privacy concerns but I'm definitely going to research that before I buy another router.
