don't let it stop you, but don't conflate open source with open core or 'democratic governance' etc.
Open source is open source. publishing code.
it does not mean
- you need to respond to peoples PRS
- it does not mean you need a github
- it does not mean you need to provide ANYTHING to the user. No warranty.
- you do not need a mailing list
- you do not need governance
Do what you want, have fun, if you have peers or other people interested in your area, feel free to collaborate in the same way you would with pickup basketball at the park, play, have fun, and leave when you're done.
