J is fully opensource: https://github.com/jsoftware/jsource

Most of jd's source is publicly available: https://github.com/jsoftware/data_jd

Is it?

Seems pretty clear to me.

As a side note, I really love the choice to dual license, and wish it were offered more often.

[jenny91 → Shared404]

It's extremely common: license it under GPL/AGPL or some other very copyleft license; get contributors to sign a CLA, then offer the library with hefty license fees for non-FOSS projects.

jd source is "open" to paid licensees only - and extra cost if you want to modify it.

jengine source is dual licensed with GPL.

[moonchild → wrycoder]

The majority of the code is available to everybody. You don't have to pay if you want to modify it. Cost is only for commercial use.

[wrycoder → SparkyMcUnicorn]

I found this license for jd itself. It is free only for non-commercial use:

https://github.com/jsoftware/data_jd/blob/master/doc/License...

The link you mentioned only applies to the jsource folder: the jengine code.

Because it’s commercially available without GPL?
