Dipende dalla licenza open source che non è indicata nella domanda. GPL offre la maggior parte dei problemi a questo proposito e qualsiasi collegamento statico o collegamento di runtime è sospetto.
Leggi le FAQ per i migliori risultati; non fidarti di altre risposte. Usare i plugin non è veramente legittimo. Molti prodotti commerciali violano la GPL in modi e amp; fondamentalmente guarda dall'altra parte.

If a program released under the GPL uses plug-ins, what are the
requirements for the licenses of a plug-in? It depends on how the
program invokes its plug-ins. If the program uses fork and exec to
invoke plug-ins, then the plug-ins are separate programs, so the
license for the main program makes no requirements for them.
If the program dynamically links plug-ins, and they make function
calls to each other and share data structures, we believe they form a
single program, which must be treated as an extension of both the main
program and the plug-ins. This means the plug-ins must be released
under the GPL or a GPL-compatible free software license, and that the
terms of the GPL must be followed when those plug-ins are distributed.
If the program dynamically links plug-ins, but the communication
between them is limited to invoking the ‘main’ function of the plug-in
with some options and waiting for it to return, that is a borderline
case.
