The internet would probably not exist outside of government and military use. Without the consumer incentive there would be no profit incentive and technology as a whole would have stagnated and the majority of computers would be akin to institutionally owned datacenters and supercomputers but with vastly inferior capabilities to the ones we have now.

However, non-networking devices would still exist and be popular, so things like videogame consoles would still be seeing some development, and possibly so would personal computers which rely on physical media being traded person to person.

I am certain technology around electromagnetic waves and telecommunications would continue to develop, possibly much slower, and that people would utilize it to create networks even though illegally, but it would be very few and niche.
