The first season of Abbott Elementary is filmed by the person who did the cinematography of The Office, and was designed as a throwback to that style as the network sitcom itself was not being made much anymore. Look at the shows that do well in reruns of the past few years, Last Man Standing, The Big Bang Theory, Mike & Molly, etc.

And honestly, while television itself won't stick around, live weekly television can still get more viewers on streaming than streaming originals.

I do know someone that writes on Grand Crew so I can't exactly be fair about it though.
