They do some things which only affect minorities sometimes. I'm rather sure that the economy breaking weapon part glitch was only done by a small amount of players, yet it was patched quite quickly. I also imagine that they posted that they may modify the economy soon in the future as tons of people go stock hugely up on parts. Personally, I can't see how people have issues with any economy parts. I have 1800 weapon parts, almost a thousand motes of light, several hundred strange coins, over 200 glimmer consumables in my vault, a few hundred ascendant/radiant shards/energies, full stacks of all planet materials, and plenty of armor materials. I honestly don't know what people spend their shit on. I look for things to buy and never find anything. I need more exotic shards, but I'm not going to petition Bungie when I know I could just grid for exotic engrams...
