Because 99% of the people saying that the "whales are manipulating the markets" has no basis at all and are just saying that so they have someone to blame for their bad trades.
They know whales are manipulating the market, scammers are creating new games to steal money from unwise investors like them but they ignore all risks and easily spend money in altcoin projects. They do it easily but unwisely because they are greedy and always want to find opportunities anywhere they can.
They are not experienced enough to know great chances they see are actually big risks that will cause them very big losses. Whales manipulate market is not important and wise investors will not lose money by whale manipulation because they buy and hold, no leverage use, futures trading, hence they are safe.
