It definitely is, even if it's justified greed (which it may be!). I'm wary yet hopeful of DeFi in general, but am not sure it belongs on Hive. Hive is inherently a social currency, and I think developing a worthwhile DeFi solution that didn't ravage the reward pool might be a challenge.
However, I'll say this: as someone who's been on the platform since nearly the beginning I am well aware that the current state of things is a MASSIVE improvement over how it used to be.
Anyway, we're still essentially in an experimental phase, so talk of any particular solution shouldn't be ruled out.
