tl;dr
The harmless books are Canaries in the Coal Mine, showing GW is capable of proudly doing what was previously unthinkably stupid to their IP, even by their already hostile attitude to their own IP
I mostly liked this post. I can see how Adventures can be seen as a canary, even if I don't agree that the books themselves are an "unthinkably stupid" expansion of the IP.
Look at what happened to Star Wars and ask yourself if the kids cartoons and such wasn’t the start of the IP doing anything and everything it cold to have mass appeal, and how that has turned out.
This post, on the other hand, is asinine on every level.
Look at what happened to Star Wars
A rich universe filled with compelling stories, or if you're talking about the franchise it's an empire with several quality films, books, video games, and RPGs. The prequels weren't good but...

The idea that the movies were bad because of the existence of cartoons and toys is dumb. George Lucas simply failed as a director. It wasn't because there was an attempt at mass appeal that the prequels turned out bad, it was just someone failing to do their job right.
As for the cartoons themselves, there are two Star Wars cartoons of note: Clone Wars (2003), the The Clone Wars (2008), and Rebels. Clone Wars was a fun show and was pretty entertaining. Aside from that, it had no impact on the canon or the IP. The Clone Wars is one of the best children's' cartoons to have come out in recent years and has added to the canon and IP in numerous positive ways. Rebels was pretty meh. That's about all you can say. It aiming for its target audience hasn't seemed to have made Rogue One, the sequels, the books, or the RPGs worse though, so you're still talking bullshit.
To summarise, I'll answer the post in full.

Star Wars is still fine. The kids cartoons have been entertaining, dull, or enriching, depending on which cartoon you're talking about. The Lego video games were fun to play and didn't make anything else about Star Wars suck more. Mass appeal seems to have worked out pretty well. The high amount of demand has generated a significant amount of Star Wars-related material both official and fan-created, a lot of it rather good.
fakedit: Freemaker Adventures was another recent Star Wars cartoon of note. It was humorous and it had engaging story and characters. It's non-canon too so its more crazy stuff doesn't ruin the setting. A fine addition to the IP overall.
