Open source in name only - This software is total bait and switch

The free version of this software is infuriating to use for anything but the most simple projects. There is no good way to implement source control without paying for the software which is outrageously expensive per seat. Talend uses the Eclipse environment but disables any useful functionality for development. They insert keys into every text file - these key values change constantly so using a source control system like Git is next to impossible. With some difficulty, you can set the application up so you can compare versions of your project side-by-side, but you can not copy Talend objects across instances of Talend and it is not possible to open two projects up at the same time in one instance.

Additionally, projects open in new versions of Talend - even minor updates - are completely incompatible with older versions. As a result, you get stuck on the lowest common version. In our case, that version was discontinued without notification from the open-source repository. Totally unacceptable.

Yes, the open-source version is free, but it is little more than a demo if you are going to do anything complex or mission critical. If you can not compare versions of projects with one another this tool is useless and they are really only using open source as a sales tool.
