When a large tech company buys infrastructure software, it doesn't inherit the seller's restraint about enforcing the fine print—it inherits the seller's customers.
T-Mobile signed perpetual licenses with VMware, the kind of agreement that looks permanent. Then Broadcom acquired VMware for $61 billion in May 2023, suddenly making those perpetual licenses a problem that needed solving—not from T-Mobile's side, but from Broadcom's.
The company is now migrating tens of thousands of virtual machines away from VMware infrastructure. This isn't because VMware stopped working—it's because Broadcom made clear that perpetual, in the new ownership structure, does not mean what it used to mean.
This is the third time the enterprise software market has watched this exact sequence unfold. The third time customers still haven't learned to price in the acquisition risk. When Oracle bought Sun Microsystems in 2010, Java licensing changed. When Broadcom bought Brocade in 2017, perpetual licenses were reclassified.
When a vendor acquisition happens, every customer's old contract becomes leverage for the new owner to rewrite the deal.
”What changes the game is when a customer large enough and technically competent enough decides the migration cost is worth the independence. T-Mobile moving thousands of VMs sends a message to every other VMware customer still believing their perpetual licenses are perpetual—you have a choice. The window closes the moment migration becomes harder than renegotiation.
