Well, they are going after them, if you read the article:

> The resolutions do not include the criminal release of any individuals, including members of the Sackler family, nor are any of the company’s executives or employees receiving civil releases.

That means Justice is leaving open the possibility of bringing criminal charges against the Sackler family.

The felonies they mention in the article are felonies committed by the corporation, which cannot be jailed, but -- due to the fact that Justice has forced the company to dissolve in its current state (pending approval) -- has been essentially sentenced to death. The company's assets (which are valuable and vital to public health) will be owned by a new legal person, a trust operating a public benefit corporation.
