True. But it shouldn't be. It's like tearing down a perfectly good neighborhood to make way for a hotel that doesn't really benefit the town.

In my opinion, that's a main reason developers should favor open source tools, they never truly 'go away'. The code is out there, so keeping it going then comes down to whether someone cares enough to maintain it. Not saying that path is all roses...

It's same. Surrounding environments will change and just because the source of a previous version is there doesn't mean you can stably run it years on.
