The reason why this will fix it is because Ctrl+Alt+Delete has a higher level of system interrupt than alternate ways to get to task manager. Ctrl+Alt+Delete fixes a surprising number of issues by interrupting runaway issues.
The content of two videos don't need to disagree with each other for the general effect to be called polarization.
The polarization isn't about income models, it's about the different kinds of content (light hearted safe content that aligns with advertisers vs extreme content that doesn't). I may have confused things by mentioning gain. The different goals of the creators was just my basic explanation as to why similar content continues being created because the effect is already in place.
I find it disturbing that you disregard the effect of capital. Advertisers are 100% focused on monetary optimization, and they're very good at driving creators to what will work best for them.
Of course content and context is important. But, money drives the content creation. Even when it isn't used to pay for the original content. Advertisers want impressions and clicks. Content creators want more viewers. The type of content aligns with advertisers goals -> money becomes involved -> more similar content. And other creators see this and want part of it.
What you're describing seems to be pretty much exactly polarization.
You get one set of creators who want monetary gain and so their content fits within certain limits. Over time this will create more similar content as they watch what works for other people.
The other set of creators have different goals and don't care about monetary gain. The popular parts of this content will also tend to local maximum based on the level of extremism that's popular.
