To give some balance to this,, try looking at the Sims games or any of the train/flight simulators on steam. I also chose a random game that came up on the steam front page, "Tom Clancy's Rainbow Six Siege" (Ubisoft 2015 game) (because I accidentally clicked on it)
The Tom Clancy game DLC (mainly just skins) comes up at £55.17 (UK pounds) for the bundle of 14 items which are not currently discounted.
The Sims 4 DLC - (EA 2014 - which the majority are stuff packs - which is things like clothing and furniture that doesn't add game features) £640.65 - again not discounted.
Train Simulator (2016) - Dovetail Games = £ error - not enough digits in steam application to display - seek parallel universes for joint effort to resolve issue.
The point is, you can take just about any game with an active official modding presence of the last decade and you'll find collectively the prices to be high, but what is a very important distinction between your example and previous games like Oblivion is very little if any of the DLC on the creation club is essential.
They are skins, armour sets, new trains. They aren't big lore packages like Dawnguard or Dragonborn. The minority that do offer extra gameplay experiences like the campfire system or quest mods are mirrors of mods that are freely available to PC users on services not connected to Bethesda or Zenemax that they perfectly legally can close down if they so choose.
The fact that consoles are not able to take part in the free modding community is a restriction put in place by Microsoft and Sony, not Bethesda. The only way for it to happen at all is with a heavily moderated service like Creation Club which costs money to operate.
If Bethesda was the evil money grabbing cabal that haters-that-hate froth in the mouth over, they could very easily close off the free versions of mods they sell. But they don't.
And as a modder myself, I've never had restrictions preventing me from making whatever mod I want (within the normal copyright boundaries), despite almost every other publisher doing that.
At the time of writing, steam records me as having spent 9686 hours in Skyrim (mainly play testing mods), in all that time I have never felt compelled to download from (or even join) Creation Club.
There is no doubt that Bethesda have made bad judgements in recent years, some unforgivable, other understandable. Evil company however that does not them make.
