Just had a look at what the IRS has to say about open-source software: https://www.irs.gov/privacy-disclosure/use-of-federal-tax-information-fti-in-open-source-software https://www.irs.gov/privacy-disclosure/use-of-federal-tax-in... lots of vague stuff, but looking at the Google result, I noticed some differences. Ah, the meta description of the page reads: Open source software, while it can be useful in many instances and appear to be cost effective, may present a security risk because open source developers don’t typically follow security best practices when developing their software. Well, there ya have it! :D
