So, if you dont work for a firm or trade other people's money then you dont owe the fee even if you never trade manually and only do algo trading.
That's great news. The interpretation we saw in this thread was obviously absurd, in that it would charge a non-professional ridiculous fees for use of data in any analytical manner. This was published in 2017. Which means all this time non-display fees were really a non-factor.
