Why is it toxic for me to need to push my code to a git repo if I start using it in my services, if I'm not trying to act as a for-profit corporation?

You can totally make profits by selling services based on AGPL code btw, it's completely fine. As long as you redistribute your derivative work as AGPL too.

There's nothing toxic in the AGPL for you as long as you don't want to make that code proprietary (even without making profits)
