This is generally the thought process that Marxists have. The USSR definitely wasn’t perfect, but it is the first real example that the proletariat was capable of uniting and other throwing the capitalist system. The USSR is fantastic to study to try and determine why it failed. Similarly China is a great resource to study to understand how capitalism can be re-established from within the party.
Most modern communist groups actively engaging in an attempt at revolution were inspired by the Chinese revolution and the cultural revolution that came after it, but none of them are trying to recreate the USSR or China because as we can clearly see those states failed to maintain a socialist character.
I work in software and I haven’t touched windows in a very long time. Even back whenever I worked on FPGA development all of that software ram on Linux, so I think you’ll find that this is very field dependent.
