The article mentions “Alliance for Creativity and Entertainment”. https://www.alliance4creativity.com/

Looks like a group that takes down piracy websites.

I assume MPA refers to “The Motion Picture Association”. They keep changing their name: “The MPA, originally called the Motion Picture Producers and Distributors of America (MPPDA) and later the Motion Picture Association of America (MPAA)”, then abbreviated to MPA.

Just clarifying the abbreviations since it isn’t really explained/articulated in the article.
