the impact is that if the developer gets to set the rules on how to interpret the license text then there will be a lot of confusion and doubt, because two projects can use the same license and interpret it differently. but while that is potentially a problem it should only affect licenses with ambiguous clauses of which there should not be many in the original GNU licenses, so the primary projects that will be affected are those that modify the GNU licenses and add additional terms.

that modified GNU licenses are problematic should not be surprising. i'd stay away from any project that tries to do that.

the impact is similar to companies calling their products open source even though they don't use an open source license. now we get a company calling their license GNU even though it actually isn't.

beyond that i don't think the outcome of the ruling will matter much.
