It could be as simple as just trying to expand the player base and getting people invested into the universe. Don't forget, Sony has many plans for Helldivers universe with a movie in production and likely TV show being discussed ala Fallout.

It's just simple math on their part. Money from sales and DLC packs plus you get so many more eyes interested in your universe who will watch your movie and TV show. Honestly, solid business move imo, they think they have a winner and if played right it could be.
