I understand your fear but I feel it is unfounded. If ISPs wanted to be content creators they would have pushed out content creators back in the 90s during the dot com boom. ISPs realized back then their value was to provide the infrastructure for the content and not monetize content or pick winners and losers in an anti trust fashion

No. That's exactly what they've been doing. Comcast and AT&T haven't been "just about infrastructure" for awhile. Their ISP infrastructure is just a portion of what they do. Comcast offers their own streaming tv service in competition with Netflix. AT&T is spending billions creating original content programming, the latest of which is the tv show Mr.Mercedes, which happens to be exclusive to, you guessed it AT&T's Audience network, a streaming subscription service in competition with Netflix.

That's not even covering the fact that AT&T effectively owns 10% of Hulu. And Comcast (through NBCUniversal) owns 30% of Hulu, though the FCC has ordered they they are not allowed to exercise any influence over the operation of Hulu. I guess when Netflix is denied licensing to air one of their shows and it ends up on Hulu instead, that's "perfectly legal" (and profitable).
