ELI5: How come it takes '10 business days' for a company to successfully unsubscribe me from emails?

Is there a logical answer to this other than "they just want to try their hardest to change your mind and/or flood you with an enormous amount of emails before they unsubscribe you"?

I can't be alone in thinking that this should be a rather seamlessly and automatic process that should take less than half a second to compute in a system's database, right?

Most companies are just being lazy and don't want to spent time on tech required to unsubscribe instantly.

Moreover, they may have scheduled some emails to you already. And just to be safe, they say that you'll be unsubscribed in 10 days, instead of removing those scheduled emails from their system.
