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 ;-)
to me all sudo features make absolutely sense (except for too loose wildcard handling), also from a security point of view. if you dislike how its 'default' settings for your distro are like, change them to your needs or seek a distro that fits your needs. other way is dont use sudo, login as root directly, nothing hinders you (maybe your distros default setup that does not assume root login, then you'ld have to give root a password maybe) or write your own sudo alike security system if you like.
if you dislike security at all, do everything directly as root (also web browsing), put nopasswd foe your user into your sudoers file or go to puppy linux (afair there is only the root user and thus no boundary between user and root) but as soon as you encounter any Problems related to user-was-also-root, you 'might' have wanted such features ... afterwards then ;-)
