Broadcom is just private equity buying products to bleed dry. Nobody thinks VMware is the future, but the folks that use it are enterprises with deep pockets who are slow and reluctant to change so you can multiply the price by big numbers and get paid big while your dying acquired product meets its end.
VMware's lock on enterprise virtualization simultaneously made it essentially impossible for anyone else to compete like-for-like using a different platform and probably also doomed VMware's attempt to start pivoting to containers.
