edit: it doesn't seem so. You just have use some weasel language:
>The final rule also bars a business from misrepresenting that the reviews on a review portion of its website represent all or most of the reviews submitted when reviews have been suppressed based upon their ratings or negative sentiment.

* Step 1, take a product with a terrible rating
* Step 2, create a new SKU for the exact same product so it has no ratings
* Step 3, get a handful of fake 5-star reviews (in some way the FTC isn't going to crack down on)
* Step 4, blast the old terribly reviewed product that now has good reviews on marketing
* Step 5, get 10s of thousands of sales, $$$
* Step 6, let the terrible reviews pour in
Repeat to step 1 (possibly under a different brand name).
Another aspect is review solicitation. eg: ios games often pop up with their own modal of "Rate us" and if you click 5 it redirects you to app store to make a review, if you click 4 or less it redirects you to a feedback form. They grease the path for positive reviewers.
If you really like an app give it a nice review.
This is just a guess, but I’m not sure getting an e-mail asking for a rating a few days after a purchase is really as “get out of my face” inducing as the App pop ups. When I open an app to buy a ticket for public transportation, that is usually while I’m actively boarding the train/bus (because why would I do this in a timely manner?). That is the least likely moment I’ll respond well to review requests. I don’t think I’ve ever been tempted to leave a bad review over one of those emails, but I’m very often tempted to do so by app pop ups. If I’m not the only one then maybe the data would be interesting?
That being said. Unless the 1 star ragers spend time on their review it’s typically rather easy to challenge by the app creator at least in the Apple Store.
