IEOs are not public offerings, which entirely misses the principle of crowdfunding, am I right or wrong?
Wrong. How can you say its not an public offering as they offered token for sale? The only thing about those IEO held on big platforms are they using lottery system to pick out the winners of their token sale since a lot of investors will probably participate. Like most investors they are confident with the listing of those IEO cause it was handled by top exchanges like Binance, kucoin and okex.
Maybe he meant to say that IEO public offering isn't transparency as ICO? Well I care less, all we want is fund raising success of new projects and top exchanges do that right, whatever happens within the exchange behind investors back isn't or shouldn't be investors problem
