If you're going to hide behind "we don't know his beliefs! we don't know why he follows those accounts!" then you don't get to assert that it hasn't been an issue- we don't know that. For all we know, there could be a dozen basketball coaches and football coaches who have noted this, and given this information to potential recruits who might not be so nonplussed as you are.
Also, as
@Hank pointed out very well, there is a HUGE difference between "Twitter follows reveal things about people, as is evidenced by how twitter and other social media companies put real dollars into marketing towards users based upon their follows" and "Twitter follows mean the person agrees with the viewpoints of all the persons they follow."
And, additionally, there is public interest value in following accounts like Donald Trump, Lauren Boebert, et al. There is no public interest value in following Faith Goldy, unless the Twitter user in question places some degree of importance on her viewpoints (i.e. white nationalism).
