Exactly. I don’t see how that could not be considered manipulative. Most other review product don’t have their own review website, but effectively do the same thing prior to posting to a public review platform (google business, trip advisor, etc). “Rate our product out of 10” where a result of 5 - 10 requests a review and below 5 leads to a “provide us some feedback”. Either action independently is not manipulative (requesting feedback or requesting review) but the combination certainly seems to be.
