That's not entirely true. You're leaving out all the times that Trion's Defiance team implemented design decisions that NO ONE wanted, or they implemented something players wanted but only went halfway, such as the weapon upgrades that weren't retroactive and consequently screwed over their veteran players. That would be somewhat analogous to Destiny implementing character beards a year into the game, but only for new characters created after they implemented the change and not for any existing characters.
It's not that Defiance never implemented community suggestions - it's that they didn't really listen or understand those suggestions and think things through enough, which often resulted in twisting the idea into something unpleasant or undesired. And of course, there are those times when they decided to do something that no one wanted, like the grenade changes, and despite overwhelming negative player feedback, they did it anyway.
In the end, it all comes down to bad management more than bad development, and Bungie doesn't appear to be suffering from that problem. I wouldn't be too surprised if it's noted in Trion's Wikipedia entry for Defiance that while they did break new ground with console MMOs, the game is also widely regarded as an example of how not to run an MMO video game.
