That is what he's saying. They released a separate free version: https://itunes.apple.com/us/app/goo-saga-free/id1156455391?mt=8
Oh I see. I understand now. I thought like they would do the same thing as some other developers do - transform the same premium version to free to play. So, we all now excited for your new games !!!!
That's correct, no need to watch ads in the paid-for version. Also, you get the Editor in the premium version (not included in the f2p version), which is a VERY strong suite of tools and we have seen some AMAZING levels created by the community!
Looks like this was re-released under a new publisher and unfortunately previous owners will have to buy it over again (or hang on to the original version, which seems to still work fine?). Such a shame because this is a great game, but two bucks isn't the end of the world. If you didn't buy it before it's highly recommended. Also I've changed the link in the first post to the new version as the old one has been removed.
