I'm a creator, and your logic impacts me financially, although I don't depend on this money, here's why: Advertisers don't even know my channel exists. The only thing an advertiser knows about my channel is that my viewers tend to watch tech-related videos, and can be associated with other related metadata produced by deductive reasoning alone. When it comes time for XYZBlenderCorp to invest in advertising, they don't get presented with a list and short bio of all the channels their ad will be displayed in conjunction with, they get presented with a friendly demographic filter with sliders for age, and combo boxes for geographic location and other classifiers.

If an advertisement for a video tutorial series teaching people how to use the 3d software Blender should happen to show up along a "Will It Blend" video, nobody should lose their job (or your money) over it. This mentality is ignorant of everything we know as technology professionals about how this business is run; so much of this process is automated and there is no conceivable way for it to not be. There are not enough humans needing jobs on this planet to manually sort video for prospective advertisers in the way you expect.
