Just an update that in bugzilla, they are considering simply removing asus.com from that list in FF 105 as a temporary fix.
Hi all, we received confirmation from Asus Security to proceed with manually removing their HSTS preload list entry at this time, and landed that removal in https://chromium-review.googlesource.com/c/chromium/src/+/3910704. We're merging that removal back to Chrome 106 and 107 ahead of releases next week to hopefully prevent any breakage for Chrome clients. For downstream consumers of the HSTS preload list this means that you should be able to stop manually patching out this entry soon, once you pull in the latest version.
Asus will separately stop serving the dynamic HSTS header soon; meanwhile there may still be some clients that visit the bare asus.com domain and pick up the dynamic entry. Such clients may continue to have issues with the router subdomain, but from what I've read this case seems rare (which may be why it didn't serve as an early breakage signal before Asus requested preloading).

Are far as I'm aware this domain has always existed on the router. There are posts going back more than 10 years that refer to it.Also, any way to verify it's truly built-in and not some DNS domain that points at the local address?
