What about the Lynx XR1? Running Android sure but officially rooted (details https://lynx.miraheze.org/wiki/Rooting_Process ) and with Linux proper (details https://wiki.postmarketos.org/wiki/Lynx_R1_(lynx-r1) ) even though experimental.
This has a serious impact on the developer ecosystem - there are still a few people who got their devices and are doing interesting work, but with so few users actually having devices the community is too small for much progress to be expected.
It's kinda similar to the old Jolla Tablet - it was a very interesting device (an x86 tablet running an open Linux distro in 2013!) but it ended up in too few hands due to funding issues & the amount of Sailfish OS apps actually supporting the tablet (eg. big screen, native x86 builds, etc.) reflected that.
Sucks, sorry to hear that :(
