Adding costs to Russia's military procurement isn't performative, but I do broadly agree with your sentiment. Pretending that Russia would acquire none of what was restricted was/is foolish.
Supply chains are complex, rife for corruption at many levels and giving some understanding how it happens seems a worthy news item for me, especially to understand the effectiveness of such sanctions, and as an educated citizen, either clamor for tighter supply-chain control, or be OK with the status quo, or ask for less control or for alternatives.
