Original sentence: Lawrence Rosen has claimed that a court of law would "probably" exclude dynamic linking from derivative works although "there are also good arguments" on the other side and  "the outcome is not clear" (on a later occasion, he argued that "market-based" factors are more important than the linking technique).On the other hand, some experts have argued that the question is still open: one Novell lawyer has written that dynamic linking not being derivative "makes sense" but is not "clear-cut," but that evidence for good-intentioned dynamic linking can be seen by the existence of proprietary Linux kernel drivers.While it is understood that static linking incompatible licenses with However, it is not clear whether an executable that dynamically links to a GPL code should be considered a derivative work (see Weak Copyleft)
Edited sentence: However, it is not clear whether an executable that dynamically links to a GPL code should be considered a derivative work (see Weak Copyleft).On the other hand, some experts have argued that the question is still open: one Novell lawyer has written that dynamic linking not being derivative "makes sense" but is not "clear-cut," and Lawrence Rosen has claimed that a court of law would "probably" exclude dynamic linking from derivative works although "there are also good arguments" on the other side and  "the outcome is not clear" (on a later occasion, he argued that "market-based" factors are more important than the linking technique).Since there is no record of anyone circumventing the GPL by dynamic linking and contesting when threatened with lawsuits by the copyright holder, the restriction appears de facto enforceable even if not yet proven de jure
