Morrowind gave you a journal with general statements or vague hints for the most part about where things would be.
Oblivion gave you a compass with exact indications on a map of where things would be.
Skyrim give the compass and the exact indications on the map, plus a spell that leads you visually to that exact location.
This isn't a condemnation of any of the games, or the way this is presented. Each game was designed with a specific audience in mind.

Morrowind gave you directions.
And a compass. And a map that had a big yellow marker on it that told you exactly where to go. And hand holding directions of "Go to this location, turn south, walk for x steps, turn left, and viola, you're at your cave that you already have a big yellow map marker for"
Oblivion and Skyrim put a quest marker on your compass telling you what direction you need to go into. The quest marker doesn't tell you how to actually get there, just which direction to go. Like Morrowind, you still need to figure out your path to your objective. I have gotten lost in Skyrim plenty of times. Not so much in Oblivion, because, well, Oblivion is essentially a big, wide open field. But I have gotten lost in Skyrim plenty. Because the quest marker doesn't tell you how to get there.
And the Clairvoyance spells is completely optional. You don't even start with it. If you are using it, you have to go out of your way to buy it. Which is your own fault if you're using it.
Morrowind and Oblivion / Skyrim are really no different in their methods. One method simply removes the tedium of constantly hitting "J" or "M" to go into your journal or map constantly to get your bearings.
