-We will mention FSL here.
+Sentry has released a draft of its ``Functional Source License" (FSL),
+which it hopes to use for its own currently BUSL-licensed software, at
+\otsurl{https://fsl.software/}.\footnote{Disclosure:
+% TODO: What is the right phrasing for the disclosure here?
+}
+The FSL prohibits, during a period of one year, uses of covered software
+to provide services that ``compete" with the original developer's commercial
+service offerings.  Following this period, the software is licensed under
+BSD or Apache terms, without the competition restriction.
+
+Several cloud-oriented software projects that switched away from open
+source licensing in the past few years also adopted license terms with
+non-competition clauses. However, these generally were not time-limited.
+% TODO: double-check whether any of them were time-limited
+
+% I think it's interesting that the AGPL doesn't seem to appeal to most
+% companies that are pursuing this kind of thing. I don't know if any of
+% them have commented on their views about it.
