they get even more revenue from other peoples contributions.

thats the whole point not more, not less.

so there is no point for “you” to pay them anything.

did you as a “premium customer” thought to be “the customer”? really? remember how little you personally pay for the service. it is mainly the ad companies who are youtubes “customers”. when you pay them for something, you only increase yt’s revenue, not more, not less, but you are not “the customer”, you are the product ;-)
