I’m trying to find a clear distinction between “Source Available” and “Fair Source”. Sounds like there isn’t any common definition for source available other than that you are allowed to read the code.
What's the point of this new term only encompassing the accompanying new license from the same authors, other than to manipulate our minds to associate "FSL" with "fair"?
FSL is a source-available license. "Fair Source" is the name of an industry lobby group. Uncritically adopting their retaxonomization of software licenses and newspeak is not advisable.
The FSL seems like a valuable contribution and can make sense for companies like GitButler and Sentry. The accompanying lobbying and propaganda (aka "PR") spoils that somewhat.
