The Gazette says the Forestry changes were "broadly well-received" - is that actually true? I have only seen complaints on the current version in the game being a fatal combination where events are too rare, not beneficial enough, and take too long to unlock rewards.
I think what the team are aiming to say here is that the changes were pretty positively received when they happened, but the number of players actively engaging with Forestry has decreased over time (as with any update) and that's where the cracks start to show in current spawning behaviour.
