Its lazy engineering. Most sites dont need such functionality, but devs are either incompetent to rip it out of libraries they use, are stuck in web design patterns from 20 years ago themselves or its a simple business decision to trade user data. When was the last time you really needed cookies for your business and couldnt get around it with (usually better) tech?

Dont blame the system (nonideal but darn good to be in place, compared to literally rest of the world where humans have simply less rights), when its companies failing knowingly basic rules.
