So I tried to read this story from The Star today. I follow The Star's RSS feed, and this story showed up in Feedly. I clicked on it and was immediately presented with the "Subscribe to read more" screen.
I understand why news organizations do this, but I don't think it's a good move. If someone subscribes to your RSS feed, that means you don't need to depend on the aggregators to drive that traffic, you should encourage that. All this does is encourage me to unsubscribe from the RSS feed and only read The Star through Apple News or Google AMP.
