Agreed, but it's the way our system works. Trending authors trend, because curation rewards exist. If you know that whales are going to vote something you'd have to be acting in an irrational manner not to vote with the whales and to do so before the whales.
Whales for the most part don't have a lot of time to curate by hand so some accounts are on auto upvote.
There is no problem with this because it's by design.
However if there were no curation rewards, then this would not be as much of a problem.
It is exactly the reason, I would not invest nor bring anyone I know here.
