There are browser ad-on that block sponsored content. Having said so, there are a few channels that provide pretty great content without sponsored pitches or with relevant pitches that might be ok-ish.
You might want to look at sponsorblock. It allows you to annotate sponsored segments, and will automatically skip them. Of course you'll also get the benefit of other users annotating so in my experience it skips just about all sponsored segments without having to do anything.
