>> Codeberg was actively positioned as an indie almost drop-in Github alternative
> What on earth are you talking about? No one, no less Codeberg themselves, would make up such fictitious comparison.
Codeberg's getting started documentation has the line, "Codeberg is not a for-profit corporation but an open community of free software enthusiasts providing a humane, non-commercial and privacy-friendly alternative to commercial services such as GitHub." [1]

Nothing in that quote suggests that it's an "almost drop-in" replacement for Github.
As an illustrative example: Proton is an alternative to Microsoft Windows, but it is not a drop-in replacement.
