Scaling enemies in Oblivion are bad, yeah, but Morrowind has the problem where you become a god so quickly that the game isn't worth playing.
Any combat skill that hits 80 to 100 is basically unable to miss and block hitting 80 to 100 makes you nigh invulnerable. Even enemies that can actually hit you end up staggered to death repeatedly.
Magic is pointless in Morrowind without focusing heavily on alchemy for the 0 weight potions or exploiting an enchanted piece of equipment that reduces your intelligence to 0-- 1 to 3 casts of any spell worth using and you're dry meaning you're back to using that 80 to 100 melee weapon skill and staggering enemies that can barely hit you to death.
Honestly, melee combat in Morrowind is as bad as spamming two handed firebolts in Skyrim. Once you get to the point that you can stagger people with your spells you're basically invulnerable as long as you control the aggro properly. Once you get strong enough in Morrowind you end up doing the same thing.
Oblivion overdid the scaling everywhere. Skyrim got the scaling a little better. Mostly just rewards scale and enemies don't scale nearly as hard. Scaling quest rewards was dumb, though. Morrowind, on the other hand, is ruined once you know where every good item is. Either you get them right away and ruin the game or you avoid them so long that you're taking extra swings to kill everything for no good reason.
I can have myself in almost complete glass armor and arm myself with an ebony shortsword within 45 minutes of starting a new game in Morrowind. It's not even that risky to do, just a boring slog of missing arrows while sitting on a building where an enemy can't reach me and then avoiding enemy spawns in a specific dungeon. The game is essentially trivial from that moment onward because nothing scales enough to be a problem (and the only scaling I know of is overworld spawns in specific areas).
