Copyright law doesn't protect "any provided value". Fair use specifically allows content creators to use copyright.

This can be for the purposes of parody, it can also be for the purposes of "reaction videos" or "commentary". The original content creators are NOT compensated for the value they helped create in a "reaction video".
