Okay I'm sorry, but let's be honest. If you're that hard up that you or one of your players can't drop a few bucks (less than the cost of one beer, much less how ever else I would spend my free evenings), about .2 seconds of googlefu gets you the modules for free.
Honestly, I'm glad they're monetizing and I look forward to buying every expedition for DMs that want to run them (with me as a player of course). More money = more likely stores will have more D&D nights rather than being overran by other, higher revenue generating games *cough*Magic*cough*.
Is it nice having stores let you play for free? Of course it is. But you know what's better? Having stores that are financially stable and that have an incentive to let D&D players have more tables.
