Some people do want to use an older version of Photoshop though. The people who do want older gimp can still pull it from somewhere. Pretty sure Adobe's been hell bent on making sure CS6 is as useless as possible.

I feel it goes the same for games (a most proprietary platform). There will be some playing pokemon Red in 2024, but most people moved on to Sword/Shield or Scarlet/Violet. Most don't necessarily care if Red/Blue is legally available (and with the 3ds shop gone, I don't think it is as of now).
