Well, unfortunately, that's not the case anymore. SW is now run by business-minded people who are taking a more corporate approach with SST and its related properties and elements, and in fact, SST isn't even the only show or thing that's been affected by this: this isn't like it was back in the 70s, 80s, or even the 90s, where there were fewer options for anybody to enjoy entertainment, and thus, shows kind of had to be made in a way that could appeal to both kids and adults, because kids and adults often watched things together. This is why primetime shows back in the day had very little sex, swearing, or other objectionable material, because entire families were watching these shows; conversely, this is always why cartoons and other children's shows had wit, wordplay, banter, and sly material, because adults would be watching with the kids and needed something to appeal to them as well. Fast-forward to today, there are tons and tons of more options for everybody out there, and a lot of it is categorized into kids only and adults only, so when there's less of both worlds watching the same things, then of course that's going to have an affect on entertainment: this is why so many kids shows today are watered-down, obnoxious, and pandering, because adults are most likely not even watching with the kids, so they don't have to worry about holding their interest as well; conversely, this is also why primetime shows today are polluted with sex, violence, vulgarity, and other obscene subject matter, because clearly kids aren't going to be watching these things, so they can throw whatever they want to at adults because they can handle it.
Unfortunately, SST is not immune to any of this, and the thing about SST is that it's not only always relied on what their research and focus groups are indicating what kind of things their target audience are into today, but it's also kept up with the times . . . and let's face it, times change - that's something that's out of anybody's control. And also considering SST continues to face more and more competition from other preschool shows vying for kids attention, they're going to have to do what they can to keep their audience watching. This is why ATC happened in the first place: the face of preschool, educational television was becoming happier, fluffier, brighter, and zippier, so SST was cleaned up considerably and lost a lot of its original inner city grit as a result.
