(This is a layered jibe.)

If you were working in military research, you got access to western computers. Academics, generally no. Companies, never. Even party members couldn't get access.

So no this is yet another victim of the priorities of communism: priority #1 is preventing dissent. And I hope you do at least understand why that means "no computers, and certainly no networks".

As to computers - it's not like you could walk into a store and buy one, they simply didn't produce them in quantity (central planning economy took a while to recognize that need). But if you could find one, access was not particularly restricted. You could also build a simple home computer yourself if you were into electronics. Schematics were published in hobby magazines and it was a cool thing to do, not something frowned upon by authorities.

Agreed on that, and access to a computer system, e.g ES mainframe or SM family was not a problem for people who wanted it. I was in high school in mid-80s. I found a fortran book in the library, and it took me very little time to get access to the university-owned SM-1420, RSX-11, and a fortran compiler. That same lab ran free programming classes in the evening with faculty volunteers.

"But by the early 1970s the idea of transcending the status quo was abandoned by the Soviet leadership, who felt the system threatened Party control of the economy."

And that was that, for the idea of connecting Soviet computer networks or directly connecting people in the Soviet union (without party-controlled channels in between).
