"quite permissive" and "open source" are terms quite far apart.

Open Source software provides certain clear guarantees to the users of that software. Even small changes to these guarantees probably render the software not open source.

This is not pedantic rhetoric, there are clear reasons why open source software should be clearly told apart from proprietary (including source available): given the OSS guarantees, potential users of a given software may make usage / no usage decisions without further due diligence. If those guarantees are modified, due diligence and risk studies may be needed, specially for companies (what if we're not a competitor today but tomorrow we want to? what do you call competitor? etc).

Open Source exists for a reason, which is to provide a firm ground on those who are good with the guarantees it provides.

Please don't try to blur the line.
