I think this is only unfortunate misunderstanding and miscommunication.
Windows users definitely getting what they're promised.
Since you have Mac, so you only think/see in Mac user's point of view. Since I use Windows, I think in Windows user's point of view.
From my view point, there's no problem whatsoever with the campaign.
For the first place, SVP is developed for Windows, the campaign was targeted for re-writing the SVP manager in Windows.
So Mac users want the same "privilege" with Windows users when the devs need to re-write core library, not just the manager?
Oh please, There ain't no such thing as a free lunch
