There are many companies purchasing their machines, however you are right that they lay of a lot of people. Nowadays they mainly use temporary staffing firms for development (except for key people of course). They actually use multiple firms, in case one goes bankrupt. Interestingly, they also applied this trick to making their machines. For example, they need a power supply, so they design one. Then they give the specifications to multiple manufacturers which build them. If one of the manufacturers goes bankrupt, they always have backups. Also if one of them does not deliver, they have backups. As you might figured out, downtime is very expensive. These manufacturing companies have started selling parts of their machines to other companies and some of them are very successful.
