Exchange listings, which is the topic of the article, and is mentioned by the person I responded to, are specifically a centralized finance thing (CeFi). Every DeFi exchange I know of allows anyone to list any token at any time. That's part of what makes them "decentralized", so the concept of knowing ahead of time when a token is going to be listed doesn't make any sense in the DeFi context. Pre-Sales are often conducted via a DeFi style ICO, which might list tokens at a certain price governed by some fancy mechanics (getting cheaper, or more expensive, over an n-week ICO window or something, dutch auctions, etc), and then eventually the tokens go up for sale on centralized exchanges, which is the "insider" event being discussed by the article, and presumably, the person I replied to.
