Which open-source projects changed their licence
Borehole reads each project's root licence file commit by commit. Of the 401 public projects in its library, 109 changed that licence in a way that changes what users may do. 63 of them narrowed it, and 21 now grant source-available terms, which are not open source. The counts move as the library grows.

Paid editions beside an open licence
These projects kept an open licence for most of their code and added source-available terms for a paid edition in its own files. They are not counted above.
- meilisearch/meilisearch: A paid edition was added under MIT AND BUSL-1.1; the rest stays MIT
Why a licence change matters in diligence
Code taken under the old terms stays under them. A buyer, a host or a fork may rely on either set, so both matter. A change toward source-available terms can restrict production use or offering the software as a service.
How this is counted
- Each project counts once, from its newest public reading.
- Only the root licence file counts, as it changed on the main line. A change on a branch counts when it lands.
- A change that no release carried is set aside.
- A move from one permissive licence to another is not counted: it changes nobody's rights in a way diligence weighs.
- A change Borehole could not confirm from the history is left out.
