Non-transparent pricing of apps in Shopify

[MikeDe]

Hi,

We have noticed that some kind of a trend started in Shopify App Store, where apps with free and paid plans list only their free plan on the Shopify App Store and then just link to the rest of the plans on their website.
This seems a bit strange, as Shopify then lists the app as "Free" even though it has a lot of paid plans available and isn't entirely free, as features are locked behind the premium plans.

In the Shopify's requirements for public apps, it says:

Apps with free and paid plans

If you have more than one plan and one of them is free, select Recurring charge as your primary billing method, then specify one of your plans as Free in the Plan pricing section. When your app appears in search results, it will be flagged as Free plan available.

https://shopify.dev/docs/apps/store/requirements#apps-with-free-and-paid-plans

This indicates that paid plans should always be listed on the Shopify App Store.

And yet, there is an app from Recurpay developer (https://apps.shopify.com/recurpay-subscriptions ), which only lists their free plan on the Shopify App Store (see screenshot), even though they clearly have paid plans in their app (second screenshot below).
The funny thing is that they set the title above their plans as "Simple, transparent pricing," even though it doesn't seem transparent at all.

This seems like a violation of Shopify's terms of service for public apps and we are wondering if Shopify's team is allowing this behaviour?
It would be great if someone from Shopify can check this and let us know here if this kind of pricing is now allowed in Shopify App Store, although in our opinion, pricing should be transparent on the Shopify App Store, as explained in the requirements for public apps in Shopify.

And yet another app which also lists only FREE plan on Shopify App Store, yet they have paid plans available: https://apps.shopify.com/return-prime . 

And it seems that merchants don't like that, as you can see in the reviews (screenshot below):
