It's something I've noticed as well and have been trying to remedy somewhat (for backgrounds at least).
But Puggsoy is right, especially for tiles, it just isn't as interesting to do. After ripping the Cheese Wheels of Doom tileset from Bubsy I was pretty burnt out with the process, more so since I ripped each tile manually through playing the game and capturing the individual tiles with Gens Kmod.
Many that have the know how and the tools to automate the process covet their tools for their own use, though that's their right earned through creating the tool in the first place, so it's also difficult for those who aren't in the know that want to rip them without putting in work in one direction or the other. Lack of a tool, lack of energy to follow through the manual route of ripping, lack of time, lack of interest or lack of skill means less tile and background rips. That's how I see it at least.
