I think these projects should just dual license as AGPL and BPL/EPL.
That way all the "it's not really technically open source" complainers couldn't day that its not technically open source.
It wouldnt substantively change anything of course, but that's somewhat the point. BPL/EPL/SSPL was always fully within the spirit of open source, it just pissed off the same large corporations who also can't stand the AGPL.
