What you wrote may be true, but IMHO this will still be seen as a win for Gun Rights. Most people will not be able to separate the content of the ad from the technical requirements, and very few people (or 'journalists') actually understand the legal issues.
Can you not agree that this is a win?
It certainly is a win for the one who wished to post the ad for the ad that they wanted to post. And the ad will contain a positive pro-gun message.
They may just change the law back too .. and then the win is still a win but no one that can be duplicated.
Almost any ad can be politicized..an ad for an abortion clinic services is certainly implying that abortions are good.
So a win for folks who want to give political opinion within ads? Right now, a win, and the court seems to give a blue print on how to make this within the law...so the court memo was very nice in that respect.
The court did not rule that one could take out an ad just to advertise a political viewpoint (almost bound by previous law) so if the petitioners feel like its a an actual of desired "win" is a question. When they wanted the ad, the law was 100% against them and it was only the change in the law that got them a win. I don't think that the petitioners wanted a win like this but a win where political ads were OK and could not be denied.
So, as the law stands now, it seems easy to make them take a political statement contained within an ad. But they can change the law and remove this tomorrow if they wanted to.
So a "win" is in the eyes of the parties. I have "won" civil cases and felt like I lost and I have lost cases and felt like I've won. It depends on what is trying to be accomplished I guess.
I see the result as a tie myself.
