Yes, for example. Or by not watching the content in the first place. Change never happened because everything worked kinda ok, it happened when things stopped working. The french revolution didn't happen because everyone was well fed.
If sponsored content stops being a viable income method, either the video will stop existing or new ways of monetization will be discovered. New ways of monetization may be "let's just collectively pay artists so they can make videos". Of course that's unlikely, but it's more likely than continuing with what we do right now.
