ASUS seems to closing it's support of open source

So I recently was going to try putting Untangle on my AC88U and started reading they're forums and found out that newer versions of the ASUS routers have different internal hardware specs now that don't allow the open source drivers to work. Same with DD-WRT. And it seems ASUS in not responding to either of these develpoers with help.
Hope we don't lose Merlin's work too.
