Filtering content is not "a form of protest", it is about deciding what content you want to see in your browser and what not. Youtube, even the paid version, does not offer much in terms of customising one's experience (imo the "algorithm" deciding what you should watch based on your history does not count as one) and shorts is a proven addictive pattern that one may not want to encounter online.
It is fine if you like watching shorts, such filter lists are for those who do not want to watch shorts.
