I don't think they think this is a problem actually. Content edited replays are actually very popular with sports fans who are time shifting. Time shifting is also an afterthought for the NFL / MLB / NHL from what I can tell. I live in Seattle but grew up in the midwest so time shift a ton of sports and it's always been horrific.
I'm more comparing Thursday Night Football and the quality of the encoding than anything. Delivery glitches are a seperate issue that I think they care about less.
NFL: 90+ minutes after the match on NFL Gameday, and it auto plays the most recent video for that team, which is always the post game interview. So you load it up, go to your team and it auto plays the "we won" or "it was a tough loss" like why the f*ck am I paying for a dvr solution when you do that. NFL Sunday Ticket: you can watch the games sometime monday after the fact but not the sunday night games. Good thing I paid well below half price for it with a disciount.
NHL: constantly shifting networks each year with worse solutions and not letting you get to half the previous games after a week. Totally useless for deferred unless you only want to watch the game a day or more after. Fubo, you have to 'record' the game and sometimes it's on a slightly different network and doesn't record. And their blackout system is the worst of all, who cares about your mediocre local team sorry you can't watch Chefs/Bills because they overlapped by some amount.
MLB: always broken at the top of the year, constantly changing the interface. You often get stuck watching the commercial break which is not actually commercials and is just the same "ohtani / judge highlight video from 2 years ago" and a "stat" about the sluggers that is almost an entire season out of date. The app resets when switching from the live CDN to the on demand one once the game ends which often resets the game and jumps you 6 innings forward, or makes the game unavialable for 30 minutes.
And EFF you if you want to watch playoffs on any of them.
