    % I put in a brief reference to MongoDB's relicensing above without
    % entering into the question of the rationale or what AWS's
    % competitive offering might have been.

  \item \textbf{Effects on outside contributions.}

    How much are outside contributions affected by using (or switching
    to) a DOSP model rather than an Open Source license?  Can any
    contribution trends be clearly and confidently attributed to
    relicensing?

  \item \textbf{Taxonomy of BUSL Additional Use Grants.}

    The BUSL default is to prohibit production use, but most adopters
    of BUSL have used AUG clauses that grant permission for production
    use that doesn't compete commercially with the software
    developers' own business, or concretely that doesn't involve
    charging for access to a hosted instance of the software.

    How similar are the different formulations of this notion? Are
    there any other permissions that appear in practice in BUSL AUG
    clauses beyond the notion of not competing with services run by or
    licensed by the upstream developer? Is there a significant
    minority of BUSL adopters that aim to restrict (and sell licenses
    for) ``production'' use more generally?

  \item \textbf{Relicensing after initial Open Source publication.}

    Is it a conscious strategy --- or at least a conspicuous option
    --- to start out a new project under a purely Open Source license
    in order to garner interest and mindshare, and then subsequently
    relicense under a DOSP license? Some of HashiCorp's critics noted
    that the company had given adopters incentives to become expert
    in, or otherwise reliant upon, the company's software while it was
    under an Open Source license, and then tried to benefit from that
    familiarity and adoption by changing the license terms in the
    future.

    If some of the most popular DOSP-relicensed projects had started
    out under DOSP rather than Open Source terms from the outset,
    would they have attracted the same level of interest and adoption?

  \item \textbf{Why has a fork of Terraform attracted so many
      contributions and so much interest compared to forks of other
      projects?} % TODO: See ref:091db178 -- maybe this question
                 % should be recast.

    It's too early to say whether the OpenTofu project will broadly
    outcompete Terraform among various audiences, but it's clear that
    this fork started off with a bang, immediately garnering
    substantial interest, sponsorships and financial commitments, and
    endorsements from various companies and developers.  However, Open
    Source forks of other HashiCorp projects are comparatively
    stagnant and underpublicized.  Similarly, other BUSL relicensing
    events did not seem to result in highly active forks (although
    some may have increased interest in existing Open Source
    competitors to the relicensed projects).

    What's special about the OpenTofu effort, or about Terraform or
    its community, that could account for these differences? Did
    Terraform's market share in its niche play a large role? Was
    Terraform particularly indispensable for its users in comparison
    to some other relicensed projects?
