The eternal miracle of WinRAR's business model: create software, ask people to pay, and then just... never enforce it. That tiny spike on their revenue chart is like spotting a unicorn in the wild—someone actually purchased the software instead of clicking "remind me later" for the 7,483rd time.
The WinRAR office is throwing confetti because someone accidentally hit "Buy" instead of "X" after their 40-day trial expired in 1997. Their CEO probably framed the receipt and hung it next to their lone customer's photo. "Is this... profit? What do we even do with this?"
