the obsidian-git plugin. Auto commits and pulls/push every x minutes. Works great for me, I get full version control and works on all my platforms (Linux, Windows, Android). You just need to be careful with your .gitignore and add at least .obsidian/workspace.json to prevent conflicts.
Probably not suitable if you store larger files, but after a year of daily usage with tons of small images I’m still below 150 MB.
Paywalled subs existed for ages already. If you had Premium or whatever it was called you could access them. It was mostly uninteresting stuff going on there.
