"General purpose": the device can do more than 1 job. The device can do whatever the software running on the device tells it to do.

As the video it explain, it would be very difficult (and expensive) to develop a device (smartphone, tablet, computer,...) that does only 1 specific thing. For example: only play video's from company X.

The way around that for companies that want to limit what people can do with their devices is to build general purpose computers and load them with spyware and rootkits.

That then creates a lot of potential problems both for the user and the company that wants to enforce those restrictions.
