Regarding "instead of": AGPL is open source too
The “problem” with AGPL is companies who want to use open source software to build proprietary stuff on top without contributing anything back. AGPL is purposely designed to avoid this kind of parasitic behavior, but that doesn't make it “not open source” quite the opposite: it's “forced open-source”.
It is indeed restricting companies' freedom though: their freedom to restrict their user's freedom.
