At the very least, in the last 10 or 15 years? Have Nickelodeon and Disney gotten lazier with their live-action products since the mid-2000s?

With Disney, while their sitcoms aren't necessarily gross or overtly offensive, they still have a tendency of being really sterile, cheaply thrown together, bland, and formulaic (https://www.hollywood.com/tv/recipe-for-disney-show-57254674/).

With Nickelodeon, while they're seemingly more willing to take risks than Disney, that isn't to say that their quality is not as consistent as Disney's. When Nick puts out a bad sitcom, then it is truly bad (https://tvtropes.org/pmwiki/pmwiki.php/Horrible/LiveActionTV), such as Fred: The Show. Also, it goes without saying that Nick became overly reliant on Dan Schneider (https://www.looper.com/618303/the-dan-schneider-controversy-explained/) despite his own sitcoms, delivering diminishing returns over time .
