Those companies were created at a very different time and are 79 and 216 years old respectively. I can't think of any other moderately successful tech company that has started in recent memory which is named after the founder, although perhaps there are a few examples. In my mind, it takes a certain amount of arrogance to name a tech company after yourself; you alone cannot possibly make it great (unlike a law firm, consultancy, hedge fund, etc.) and naming it as such severely discounts the perceived worth of other employees.
