<br>
In my opinion it is GDAL's mandate to favor projects that use the same type<br>
of license than GDAL itself. Both proprietary and more copy-left licenses<br>
makes it a bit harder to handle the whole system. Individual developers may<br>
have their own opinions about what licensing model is the best when it comes<br>
to principles, but I would rather see GDAL as a project to be neutral "We<br>
prefer BSD, but we respect also libraries with other licensing models. To<br>
respect does not mean that we want all of them incorporated". <br>
<br>
If a project selects BSD it is clear from the beginning that anything that<br>
is allowed by the license may happen. <br>
<br>
I don't agree that GDAL supports proprietary drivers more than copy-left<br>
drivers. We have told you that it is quite OK to have a new JP2Grok even we<br>
would prefer to see improvements in JP2OpenJPEG because it is BSD like the<br>
rest of GDAL. And that we are a bit sad because of AGPL and there are users<br>
who can't use Grok, but nothing harder than that. That we prefer BSD is<br>
consistent to our message to the MapInfo team that suggested to add a new<br>
proprietary driver <a href="https://github.com/OSGeo/gdal/pull/3447" rel="noreferrer" target="_blank">https://github.com/OSGeo/gdal/pull/3447</a>.<br>
<br>
To suggest that we should remove all existing proprietary drivers if we are<br>
not very eager in accepting one more JPEG2000 driver is obviously meant to<br>
be a provocation but I do not know how to react.<br>
<br>
GDAL project does not easily drop existing good drivers which have an<br>
established user base. We may drop JP2KAK some day because it is not really<br>
actively maintained but it is quite a good driver even it does not utilize<br>
some improvements introduced in latest latest KDU SDK versions. So perhaps<br>
it is kept as long as it is possible to compile. If Kakadu was open source<br>
we would be in the situation that you described "If driver A is faster and<br>
more feature rich than driver B, they will want driver A." Unfortunaly very<br>
few users can afford to select driver A in this case.<br>
<br>
We do remove old drivers <a href="https://github.com/OSGeo/gdal/pull/3505" rel="noreferrer" target="_blank">https://github.com/OSGeo/gdal/pull/3505</a> and it<br>
means goodbye to Jasper.<br>
