They aren't inherently bad but they are inherently easy to misuse and implement poorly. Which actually does support restraint in deciding to use them.

One thing I see frequently which is preposterous is infinite scroll on pages that actually have a footer which is pretty much impossible to access.

YES! For sometime Facebook had it! I needed to access the FB's dev section and it was like a clicking contest. When they moved it to the right, I had already memorized the website.

Pretty sure Facebook used to do that with the footer.

The workaround to get to the "developers" link was to mash the escape key while scrolling. Those were the days.
