It's not something that can be found again when servers are gone since no one cares about some titles. in my opinion it might almost be guaranteed that allot of crappy titles will vanish.
Just because you do not like it, doesn't mean someone doesn't. Maybe some kid got to play some dumb game when they were a kid on a website, or as a download only game on a console and they loved it. Without any sort of preservation, that kid wouldn't be able to replay that game 10-20 years from now.
This also applies to series collectors and historians/archivers of series. I already know there are at least a dozen Transformers online games that are lost or will be lost. No matter how dumb or crappy the game was/is. It is a part of the history of the series that no one can play, watch, or even really know what it looks like. Same goes for a lot of phone games. There are some people who are active in attempts at asset retrieval, so far I have participated in and seen being done. So far, I am not aware of anyone being able to archive them completely, even in a state where they are playable or not-playable requiring modification.
This activity is in the legal gray area, and falls under the umbrella of piracy for certain. But it is because of the understanding that companies are not interested in retaining this information or releasing it. The instances where even a physical client media was available and the publisher had released server netcode to allow the program to be used after official support has died is extremely low. If you want to make a console comparison, think about SegaNet, Satellaview, and Fujitsu's WorldsAway just to name a few.
