It's also abused by soo many devs, just wanting there app to be seen 24/7 by the users, regardless if there app gains anything from being in the menu bar. That's why many users run out of space. Most people don't look at settings or ways to remove them (if they even give an option), so they quickly fill up the menu bar. Back in the day without a notch, people would have so many that some menu items would disappear too.
