Full disclosure: DivestOS is my project. Hopefully I’ll have FP4 support sometime in the future.
iodeOS is far from open source.
The only repositories on their GitHub and GitLab are some forked apps and the device trees.
They do not publish their platform repositories, their repo manifests or their kernels.
Their big feature, the adblocker thing, is also proprietary.
iode · GitLab < forks and device trees
iodeOS · GitHub < used for hosting their OTA images and fdroid repo
Their Firefox fork is currently missing at least 2 known critical security patches.
And I can’t even tell you how far behind their Chromium version is, because no public repos.
I can only post 2 links, the PrivacyGuides discussion is #616.
github.com/privacyguides/privacyguides.org/discussions/616
And my Firefox dates comparison is on my site, linked from the our apps page.

that you’re either for them or against them
Personally I’ve tried to repeatedly collaborate with many projects.
The goal of DivestOS is to bring as much benefit to all users, not just those who can afford a Pixel.
You can see this for example with my CVE patcher, I’ve reached out to over a dozen projects to offer integration help (to sad response).
I actually emailed Fairphone a while back with regards to missing CVEs on the FP2 to zero response.
