If you want a private desktop OS you either use a debloated Windows which can break, or Linux but it’s not always easy to use, but I’ve never heard of anyone use a de-googled Chrome OS, smth like Graphene OS but for desktops. I’ve actually never used Chrome OS but to my knowledge it’s open-source, easy to use and can already run Android apps making it a strong option
A ton of them are supported by coreboot. I dont know if this is an individual or a community but here is where you starr to free your chrome device:

Mrchromebox is the way. I have an old Acer Chromebook that I use for distro hopping, was using MX with KDE Plasma for a while with no issues. This week I’ve been trying to get FreeBSD to work on it…well I got FreeBSD to work, but I can’t seem to get any DE running with it…yet.
