The problem with fusion is the engineering difficulties of upscaling the technology. This has nothing to do with some vast conspiracy or attempt to control who makes money from it, it has everything to do with the fact that it is very difficult to safely generate and contain the plasma. If you could solve the technical difficulties it would get built because it would be hugely profitable.
There is nothing in the article quoted in the OP that suggests that lockheed are any closer to the goal of upscaling a fusion reactor than anyone else working in the field.
