I think it's safe to say that the majority of people in science, technology, and engineering fields are now comfortable with the idea of open source software. But this wasn't always the case, and there are still many people out there that are not comfortable with the idea of open source software being relied on for important, mission-critical tasks. Even if an open source package has been shown to be dominant in terms of accuracy or performance or some other metric, there are those that would choose a paid licensed, closed-source alternative simply because it has a company name and a support contract standing by.
Someone entering this field, starting to pick up new skills, would discover soon enough that it is hard, if not impossible, to get by in bioinformatics without open source tools. But say you are communicating with a consultant, or someone in a IT, technical support, legal, or otherwise auxiliary role. Are there any quick statistics or objective explanations to help convince them that they should not waste time avoiding open source?
Specifically a number that might help sway skeptics is the percentage of biomedical organizations that utilize open source tools somewhere in their analysis. Is there any way to even roughly estimate that value, or something similar?
I've found that subjective arguments about open source's ability to track bugs and collaborate with a variety of developers with different use cases have not worked, so it would be great to have some objective facts that make the case clear.
I have trouble even finding paid, closed-source packages for genomics. (That alone could be an argument.) But for example, I have seen people outside the field place higher value on packages like CLC Bio because the company "owns" and supports the tools contained within.
