The complaint in the article says that Meta is required to consider the impact of its actions on the diversified portfolios held by its shareholders. The plaintiff asserts that it's not about having a detrimental impact on a generic diversified portfolio but rather the various diversified portfolios held by its shareholders.

The specific complaint is that Meta ignored the concerns raised by its shareholders about the impact of its actions on the broader portfolios held by its shareholders.

Once again I do not think this case has merit, and lawsuits of this nature almost always fail, but we should at least take some time to understand what is actually being pled so that we can object to it with a firm standing.
