If they bring back Unity's original co-founder and CEO (David Helgason) and restructure/debloat the company, they might have a chance of reacquiring some of the goodwill. People still want the "old", pre-IPO and pre-Riccitiello Unity back.
They can restructure the company, but they can't restructure their incentives.
It would really turn the energy around to cut the bloat, bring in Helgason as CEO w $1 salary but boatload of call options, have him explain a model that encourages indie devs while milking cash from gaming giants, and works towards a sustainable income statement for Unity.
