So Bungie said there would be no monthly subscription fees and then most of us instantly thought micro-transactions. I personally hate in-game purchases like that (unless its just new colours or something), the pay-to-win thing is so unfair and completely ruins the game. So, as an alternative, how would you feel about in-game advertising? Imagine walking around a city/village or whatever and seeing a banner advertising Fairy Liquid! IMO this is a much better solution as its much safer than relying on people spending extra money on useless goods and Bungie can also monitor the most visited places within the game so as to place adverts there thus increasing views and in turn profits.
