That's open source. The early implementation of an idea is broken. Someone creates an alternative which fixes the problems. The alternative often doesn't gain the same traction and the original continues as the broken dominant implementation. But the alternative is also broken, but maybe in different ways. As design decisions pile on, the broken spreads. In the end, we again learn that software sucks. It will always suck. For people who don't like reinventing the wheel (or relearning the reinvention) stick with the "good enough" and focus on building cool stuff.
