I'd argue that this doesn't actually make any difference. None of our price moves are ever due to anything but rising price of BTC.
Having the stabilizer and one other working at keeping the peg is meh - good for them. I'd rather have one or two large entities doing it than trust that the community as a whole could do it (because we wouldn't, and it would break, worse and more often than happens now).
Honestly, this all feels like a bit of a nothing-burger to me. 20% gives us nice returns and hasn't caused a dip in the price. Price action before APR changes didn't push us up natively - again, we only surge when BTC surges.
So all of the complaining about 20% and not being free and blah blah blah... it's all irrelevant and theory-crafting. It hasn't factually hurt us, and not having it won't factually help us, so who cares.
