It would be interesting to know why the main window does not have "GHIDRA" in the title. And also interesting to at least see maybe the analysis menu or a decompilation. So far I wonder if it is just another interactive disassembler which based on the screenshot can hardly be compared to IDA. Well we wait a couple more months :D.
Probably they are trying to get some goodwill releasing a dated but reasonably relevant tool which has some unique advantages since they will be the first intel outfit to do it, can contribute to academia with a research paper, and show they are not always in sabotage mode. As well given the dumps, probably they refocused their efforts and energies. I used to assume they had a near perfect decompiler which could even handle self-modifying code. I am still quite certain this exists but its very upper echelon stuff by those who intensely all surveil each other with invasive subvocal monitoring not stuff that could be leaked by your average contractor. We just get to see some mid level breadcrumbs occasionally at best. Anyway the system has a nasty defensive mechanisms and maybe its easier to get some RE slaves to do the dirty work than make and hide "perfect" tools. We can only speculate about a lot of the ruling class secrets but rest assured money has never kept them in power since Ancient Egypt and on - they always kept reasonably large technological advantages hidden up their sleeves.
