Some of it is still linear like broadcast, if that's your personal distinction. Pluto, for instance, has a surprisingly large audience. The return of linear TV is also a big buzzword in streaming today with a lot of the majors experimenting with or already reintegrating linear TV options (partly because services like Pluto proved it out, partly because some of the streamers realized linear again is the ultimate endgame of Netflix-like binge watching and YouTube-like autoplay and want to skip the intermediate steps and return to the original thing).
Yes, there definitely is linear programming over the Internet, both free and paid.
We've finally come full circle: Linear broadcast TV -> TiVo (finally, no more missed episodes!) -> VOD, i.e. Netflix, Max, Hulu etc. (why linear broadcast everything to everyone if we can just OTT stream everything individually?) -> FAST, i.e. Pluto TV etc.
