This observation is often made when an OTC stock gets suspended. Problem is it is an apples and oranges comparison. The “grey market” is both the birthplace and deathbed of stocks. Stocks awaiting their 211 approval following an S-1 offering to “go public” start on the greys. In fact, EVERY publicly traded stock starts on the grey market.
But on the grey market there is also another type of stock found there...SEC registrants who have been suspended. So while most stocks starting out are successful getting to quoted trading, suspended stocks are only successful about 1 in 1000 suspensions.
Of course they forget. Remember the grey market is where stocks go to die so using their logic, I expect Facebook and Twitter to get revoked very soon. It's inevitable supposedly.
