This article is legit. Letting app creators know where their installs are coming from is important information. (Expensive advertising or free word-of-blog?) It’s what it doesn’t mention that raises my eyebrow. They have to be tracking unique installs by device, to make sure that it’s not some guy in India continually re-installing the app for pay. There’s no mention of user security and that there’s no way to track the provided data back to an actual device.
Now, that could be because that’s been worked out years ago and it’s not an issue, or … it’s an afterthought.
