Why 7 wonders became premium??

[PaulHudson]

How long games will be premium?
Forever?

For example 7 wonders was for free and now its Premium. Will it be Premium forever or soon its gona be free again?
Thank you

Hi,
For the latests months (years?) 7Wonders has been Premium;
and 7Wonders Duel has only recently been added to BGA for Premium
(that being said you always can join a Table as non-Premium...)

Both 7W & 7WD were available for everyone only this weekend, as announced

7 Wonders and 7 Wonders Duel were free during Spiel.Digital last week, after that returned to Premium status again, as before.
