This! That's why it's so important to send a quick email or message to their sponsors. I don't think Jonathan himself gets off on these kind of things (he enjoys dressing in women's clothes and all that, but that's between him and Anna and I don't care as long as the kids don't feel embarrassed, -yet) but he knows that this kind of content brings views and engagement, he doesn't care where this engagement comes from as long as he can show companies those fancy stats. That's all he's after, in my opinion. (plus it feeds his ego)
We need to differentiate between YT and other companies. The most important thing for YouTube is viewer retention, meaning: how long a creator can keep a user on YouTube watching videos. The SJ's have an extensive back catalogue which does give them a big advantage, that's why they've both started their channels again, YT ad money is a quite steady stream of income and isn't really affected by what scandal they're involved next and the more videos you pump out every week, the more ad placements there are. Subscriber count or views aren't the most important metrics when it comes to YouTube wanting to put adverts in your videos. So in short: They will keep making money from YouTube ads BUT their main income has always been product placement, sponsorship deals, free stuff, and they are definitely hurting bad in that department, as those companies DO care how many subs and views someone has and if someone uses his daughter as weirdo bait. I know they've barely had any deals recently, but if you see a company working with them, it's so, so important to let them know who they are working with
