>It only works if everyone in the ecosystem is honest

In general, applying this to anything with the general public, I don't expect it to work. This is why we have laws, licenses and rules in the first place. You can preach all you want but it won't change humanity, you need something concrete, something written and agreed, like a license.

Not all licenses protect the freedoms and rights you're used to in other licenses, and it needs to be taken into account when adopting any project. License terms that don't guarantee any sort of support or updates when you need them aren't in consideration at that point.
