No it didn't. Technical issues arise all the time, in all manner of projects, and are fixed all the time without losing business. _You_ lost the customer because either a) you didn't properly communicate the technical problems being resolved, and/or b) did a major version deploy without verifying and testing beforehand. Stop projecting your failures as a developer on someone else.

Open source software is powerful and comes with no guarantee - we are all provided with enough rope to hang ourselves. This freedom is what enables us to build really cool stuff. But it also means we're all responsible for using it correctly in our particular project contexts.
