you need to remember that some are incompatible with each other

Answer 2

Nobody forbids then to take and change the license.
In general, "it will be developed by Open Source until a certain point" this usually means that the project is UG.
If you are ashamed to take money for your share and you do not want to disgrace yourself, but nevertheless want to publish it for some reason, then 99.99% of it will remain a miserable share. And the source codes are huge strangers, don’t understand what projects - by themselves, no one but you is needed, by and large.
A normal project should be initially commercial, but with a sales funnel, marketing needs to be taught.

Answer 3

MIT , BSD .

Answer 4

BSD.
Provided that you are not going to use someone else's code in your project, especially GPL / GPL-like.

Answer 5

IANAL, TINLA.
Do you (a legal entity) write something there, and then write something else based on what has already been written? Great, but what does the license (free or not) under which you intend to publish intermediate developments have to do with it? You cannot bind yourself to the terms of your own license.
Or do you mean to say that you intend to accept contributions from third party developers and users? Since, as I see it, you yourself do not yet fully know what exactly you want to do with your free work, it is useful to be able to fully dispose of it without being bound by anyone's property copyrights.
To do this, you need to either persuade third-party developers to transfer exclusive copyrights to their contribution to you (they often do this, see how ownCloud'a does it , for example), or persuade them to transfer their contribution to the public domain (or a state close to that , in the form CC0 it is generally recommended to do this). Of course, you will scare away some potential assistants with this, well, the development of proprietaryism is such a thing.

GPL
