The reason why Klickywelt members can see the catalogue of new releases early is because they are a sizeable numbe of collectors each of whom has a sizeable collection, i.e. they are a major market element, even within the context of the German market.
The reason why Playmobil don't want the pictures of the 2024 releases shared is because the annual German toy fair at Nurmeberg occurs round about this time of the year (30th Jan to 3rd Feb) and they don't want pictures released before the wholesalers and retailers have seen what's coming out.
So not "entitlement" on Playmobil's part (and in fact they hold the title to the pictures), but keeping your customers of all sorts on your side.
