BRUSSELS, April 15 Reuters U.S. chipmaker Broadcom is being asked by EU antitrust regulators about changes to newly acquired cloud computing company VMware39;s licensing conditions following complaints from a spate of EU business users and a trade group.

The EU competition enforcer said it had sent requests for information to Broadcom to investigate the issue.

The European Commission has received information suggesting that Broadcom is changing the conditions of VMware39;s software licensing and support, a spokesperson said on Monday.

Beltug, a Belgian association of business users, and its counterparts France39;s Cigref, CIO platform Nederland and VOICE Germany last month took their grievances to EU antitrust chief Margrethe Vestager, EU industry chief Thierry Breton and Commission President Ursula von der Leyen.

The groups in a joint letter complained about sudden changes by Broadcom in policy and practices which allegedly resulted in steep price increases, rebundling of licences, a ban on the reselling of licences, and a refusal to maintain security conditions for perpetual licences.

Trade body CISPE, whose members include Amazon and 26 small EU cloud providers, has also complained about Broadcom allegedly unilaterally cancelling license terms for essential virtualisation software.

Some of VMware39;s changes were already in the pipeline even before its acquisition by Broadcom, a person with direct knowledge of the matter told Reuters.
