As soon as I heard Unity was back pedaling, I thought “there’s part 2 of the plan”
1: release abusive payment scheme to see just how much push back they get. If push back is minimal or losses are acceptable, end here and enjoy the profit.
2: if push back is strong, implement the actual payment policy that is still a significant increase, but less significant than the one above. And wait until the controversy blows over, which it will.
Yes, lots of developers will leave, lots of developers will choose a different engine for their new games, but there are a ton that will decide that it isn’t feasible to switch engines and plenty that will just eat the added cost. The thing that remains to be seen is just how much damage Unity has done in terms of new projects choosing other engines over theirs.
