This section in the 10-K came just after the June 2021 shareholder suit. The chronology fits with being recent even though it’s unclear when the subpoenas were issued. Issuance seems highly coordinated around 10-K timing for release. One part seems to be an inquiry (SEC) that surfaced from a different department’s investigation (DOJ). But that’s a guess.

Long arms do seem to be involved, whether a competitive force or string of someones bending certain regulatory ears. Without specifics it’s hard to assess which elements are vulnerable, from an individual in company to how unencumbered the company will continue its pursuits.
