This is Ian I am a big of your products definitely inclined for having a solid device that warranties having a solid performance, as much possible customize and of course that It can have the direct posibility of running with Open Wrt update to the latest version.
Even I know the developers of Glinet are doing a great effort for moving out from snapshot version hook to the firmware of so many products.
I heard this concern from so many friends as glinet or pinephone are not complitely a 100% opensource.
So here my recommendation for creating a device with Atheros that definitely are not focused anymore in great interface of GLinet, just something that you can wipeout right away as you buy and install Openwrt. (Bc for licenses you cant directly sell it with Openwrt).
You may save a time, only investing in assure one product that only works (obviously with the right hardware as I mentioned Atheros before). It may seems market risky but there is a lot of people who is looking exactly one router to buy and modify so I think if the device is as powerfull or even better than Flint you could in the right path of the market. When I talk about customize maybe I wouldn’t go so crazy as Omnia Turria because most of the people can’t afford that… but there is many things that can be done to not increasing costs and focus on the esential, a solid performance running on Lucy with the most updated version of Openwrt.
Reply this post if you are seeking for a 100% open source Openwrt product.
Hope you don’t take this as a negative feedback, and just to clearify that I know I can access Luci from the advance features of the main interface but it is not the same to me.
