I don't think any of the Vsync solutions are religious anyway.
(computing) not restricted to using one type of hardware or software
Adaptive sync is platform agnostic, the problem is nVidia. They are avoiding supporting it because they're nVidia and must exhaust the proprietary nonsense first.
But G-sync supports a wider range of refresh rates than adaptive sync

That isn't relevant to the OP. nVidia ARE avoiding supporting it. Adaptive Sync IS platform agnostic, Intel will be supporting it.

I think it is relevant. If Adaptive Sync is of the same calibre as G-Sync, then NVIDIA's position is pointless.
But if NVIDIA have determined that a module is necessary to get the best performance, and Intel and AMD take the approach that you don't need a module, and instead they prefer the cheaper solution of using options that already exist in DP spec, then that's a big hurdle to get over.
The same could be said for why Apple don't support Android applications.
Apple iOS is a proprietary OS which is specific to their devices. They don't support anything else; where Android is written to be more platform agnostic.
NVidia believe that their solution is the best solution (why wouldn't they). Thus there is no reason for them to support a "platform agnostic" solution.
Why don't AMD support G-sync and make it the platform agnostic solution?
If nVidia joined in with a-sync then how long do you think it would take to be superior to G-sync? My guess is not long.
Aside from the slightly wider range and possibly allowing a higher overclock, GS doesn't offer anything extra over AD/FS, well at least it certainly doesn't demand the extra £150+ price tag imo anyway.
Also AMD Freesync is based on the industry standard Display Port Adaptive-Sync technology.
Intel is going to support Adaptive-Sync not freesync they are different.
However this method needs to be constantly updated in the firmware & drivers for the video cards in question to be able to support the range of enabled monitors.
With G-sync it is the other way around, the G-sync module needs to support the monitor it's sitting it and send communicate with the driver / graphics card in a set way.
