You don't actually need to focus on this. As a retail investor your going to get filled at NBBO (National Best Bid and Offer). The people writing things that make you think otherwise are selling irrational fear.

It's no different than how local news makes people think that crime in the US is at an all time high by reporting on it all the time when, in fact, crime has been dropping for decades.

Don't buy what the fear-mongers are selling.
