(Apache2 has a number of explicit clauses that make it preferable for open-sourcing commercial software.  For example, it automatically grants a patent license for any patents used by the software, but then terminates that license if a licensee sues <i>over that software only</i> [as opposed to React&#x27;s original patent clause, which could be construed as terminating the license if you sue Facebook at all and got them into a lot of trouble], so that contributors can include patches covered under their patents without poisoning it for everyone.  It also defines that all contributions are licensed under Apache2 as well, so that if you take patches and then incorporate them into your commercial software, the contributor can&#x27;t turn around and sue you for them.  And it&#x27;s GPL3-compatible, which many other permissive licenses aren&#x27;t.)
