Just STOP playing it. Make them notice your disappointment. If a Bungo veteran like myself and many others can do it, you can too. There's other games out there worth giving your time - games that don't have microtransactions, games without lootboxes, games that aren't overshadowed by shitty business practices. Casual players will come and go but you can stop encouraging Bungie's decisions by NOT playing their game. Actions speak louder than words. :)
