No they don't? The whole article is about the fact that they're using a loophole. I just checked Zomato's Play Store page, it doesn't say it collects "other installed apps", which is what it should be saying. For example, one of the other listed apps does have this. That's what it should be listing: "Installed apps".
I'm sorry, I gave you too much credit. Is your argument that the "ACTION_MAIN" intent filter somehow gives you access to all installed apps? Do you have any reasoning or Google API documentation to support this?
That is not true, as those apps declare that they collect app activity data in their Play Store page though.
