Github vs Gitlab vs Codeberg

Hello everyone. I recently started using github to be able to publish grav plugin.
I didnt know how to use git or github and that was a good test drive for me.
Now i know basic usage at least. It is nice to use really.

Here is the topic:

i found gitlab is foss and better than github on this topic but codeberg is also foss and more libre than gitlab so it is floss i think?
i guess codeberg is better to use for me since it is more libre and why not?
i ask really why not? anyone know what would i gain/lose by using either of those?
so gitlab vs github vs codeberg = ?
im waititng for comments ^^

While at it i want to ask, do i have to use github to publish theme and plugin for grav? Cant i use anything else like codeberg?

Only GitHub is supported if you want to publish your plugins to GPM. Otherwise I would've migrated to Codeberg a while ago

There's nothing forcing you to stick to Github, you can surely sync git repositories back and forth AFAIK https://codeberg.org/Recommendations/Mirror_to_Codeberg
