This is the same problem with something like WoW classic... you can get the game that existed 15 years ago. But even if it is the exact same game, the world itself isn't. Online walkthroughs, videos, modding knowledge, theory crafting, etc. Those things are much more fleshed out today so even if the system didn't change 1 bit, WoW Original vs WoW Classic are really two separate games.
Likewise... if you dropped Google Original down today? I'd love to see how fast it would get owned by these sorts of operations that have had a decade+ of practice in skills like CEO that didn't exist in 2010.
You had more relevant results? That wouldn't change because companies live and die off of SEO now and didn't then. Highlighted ads are such a small thing on the website when compared to getting a full front page of the same Stack Overflow answers in 20 different websites that all have SO cloned and reskinned.
