That’s the beauty about open source: it isn’t beholden to the whims of anyone. If disagree with the Linux Foundation, you’re free to make your own independent fork. Others that agree with you can then start contributing to the fork. And this isn’t a purely theoretical scenario as it has happend with other open source projects before.
I don’t think logseq has fully automated synchronization, at least it didn’t when I started using it. What it does have is the option to automatically git commit changes. You can then synchronize through a remote repo. It isn’t fully automatic and requires a remote repo you can trust with your data but it works great for me
