They don't really need the goodwill; at least, the current board doesn't need it. The amount of lock-in a game engine has on a game being developed with it is staggering. Game devs already using Unity, or at least making assets for Unity, are going to finish the projects in Unity.
The next gen won't be using Unity though, but the current board will have picked all the pockets they need to pick by then, and be retired on an island with their grift-money.
They really need to make it easier for retail investors to vote, there is no reason it couldn't all be done online. But I get like 20 different packets I need to mail back in? Most people won't ever take the time for that.
And even then people will be keeping a wary eye on them. Same thing happened with Wizards of the Coast a while ago. It's good to see that these companies can still be forced to back off, though.
