If he actually has filed these reports and Asus is not responding, I see no reason for him to stop.I think you've made your thoughts on ASUS/Merlin quite clear here already - https://www.snbforums.com/threads/gt-ax6000-vs-rt-ax86u.78498/page-3#post-816584
I do wish people would stop reacting/responding to these posts
Perhaps @RMerlin could try repeating said case-study described above and get in touch with Asus to work out a solution, or at least see what the holdup is?
