G-SYNC Vs FREESYNC VS Adaptive-Sync

[chaparral]

Can someone here explain what the differences are going be between these three

Nvidia = G-SYNC

AMD = FREESYNC

VESA Open standard = Adaptive-Sync......(VESA has officially added a feature called Adaptive-Sync to the DisplayPort 1.2a specification, which means that a G-Sync-style adaptive refresh mechanism could be built into nearly every new desktop monitor in the coming months and years.)

And Adaptive-sync is amd Freesync.

But aren't AMD making out that Freesysnc is meant to be there own special thing....

Now it Sounds more like AMD just trying to steal the credit from VESA Adding Adaptive-sync to the DisplayPort 1.2a specification...

Is there any known reason why Adaptive-sync did not get added to the HDMI version 2.0 specification ?

Why DP only
