Interesting analogy, but I think it's too sinister. Drupal is not a religion business, it's an actual shipping product. The reason backwards compatibility is maintained is because people are actually using it.

Personally I haven't touched Drupal in 7 years because I prefer working on bespoke hand-crafted solutions, not the cookie-cutter cram-in-everything-and-a-forum-for-$5000 type of sites that Drupal excels at, but at the end of the day that's a big market, and no one serves it better than Drupal. I have a lot of respect for the codebase even if I don't want to be involved with it anymore.
