Comment on The IRS Tax Filing Software TurboTax Is Trying to Kill Just Got Open Sourced

  Correct. They’re bad. And if someone releases code under CC0 that has patented stuff in it you may be liable for using their patent without permission because CC0 says in section 4a,

  No trademark or patent rights held by Affirmer are waived, abandoned, surrendered, licensed or otherwise affected by this document.

  Compare that to MIT which is considered to implicitly grant patent rights by saying you may deal in the software without restriction. Apache specifically gives you explicit patent rights in section 3.

  Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by such Contributor that are necessarily infringed by their Contribution(s) alone or by combination of their Contribution(s) with the Work to which such Contribution(s) was submitted. If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed.

  So the problem is that CC0 ik it’s public license fallback specifically says that it does not grant patent rights.

  CC0 is a trap for software. Please avoid it. Please encourage others so avoid it.

  To the extent of my knowledge, the only public domain dedication with permissive license fallback that is approved by both FSF and OSI is the WTFPL. Which is also a crayon license. Public domain is a weird concept and not all jurisdictions have it and not all jurisdictions allow you to manually put things into it. This is why they need the permissive license fallback. You’re better off using a well known and well understood permissive license.

  Correct. You release something under CC0, someone else sees it, patents it, and sues you.
