It's certainly true that the Filterset.G folks don't like the Adblock Plus folks. It would take them three seconds to make it compatible with AdBlock Plus. It's the exact same file format. They just need a static URL for the file, which could be provided with a "latest" link. They have one, but it contains the filename instead of the data. All my script does is link you to the latest file.

I'm not sure how you can conclude from all of that that the Adblock Plus folks don't like Filterset.G other than their technical issues. Regardless, you can still use it. You can even still use the Filterset.G updater, although that bypasses one of the very nice features of Adblock Plus.

Other than "what I have currently works", none of your arguments seem to hold water to me. But you can ignore the updated features if you wish. No skin off my nose.
