Filed in New York County Supreme Court on Aug. 29, AT&T’s lawsuit states that Broadcom is “threatening to withhold essential support services for previously purchased VMware perpetually licensed software unless AT&T capitulates to Broadcom’s demands that AT&T purchase hundreds of millions of dollars’ worth of bundled subscription software and services, which AT&T does not want.”
  ...
  But many customers, AT&T included, remained on pre-acquisition VMware contracts that featured perpetual licensing. Now, though, things are coming down to the wire. Broadcom’s contractual obligation to provide support services to AT&T applies through Sept. 8 — four days from now. 
  ...
  And yet, AT&T says, “under an amendment the parties signed in August 2022, AT&T obtained the right to renew the support services for ‘up to’ two more years at its ‘sole option’ as long as it does so prior to the end of the current term.”
  AT&T is exercising that option for at least one more year but Broadcom, it alleges, “is refusing to honor AT&T’s renewal.”

Sounds like AT&T did put in place longer term agreements. It is Broadcom who is altering the deal.
