Let me be clear: Broadcom did not buy VMWare to go into the virtualization business!
They bought them with the following plan:
1. Jack up the prices (by an insane amount) while reducing costs in extreme ways
2. Most customers are large enterprise users: they will change eventually ... but it will take the time, and in the meantime they will pay
3. Eventually everyone leaves VMWare ... but Broadcom (or rather the people behind it) have already pocketed enough from step #2 to pay for acquiring VMWare in the first place, plus a profit
4. VMWare, even with few/no customers, still has tons of assets like real estate: you liquidate all that and now you've made a massive profit over what it cost to buy VMWare
This was not some secret: it's a playbook Broadcom has used on acquisitions before. Maintaining a virtualization company was never their goal: it was to make money fleecing the company's corpse.
