I've been using it since 2016, and none of the new features that I don't use have negatively impacted me.
Nitro, Shop, and Quests. What are these even?
Even their changelog page is wtf (https://discord.com/tags/changelog)
Shop is where you can buy additional customizations.
Quests get you exclusive unlocks for various games.
Shop is where they sell customization stuff.
Quests let you earn currency you can use to buy customization stuff or nitro instead of real money.
I don't think there's a significantly better way to do whatever they are doing, and I don't see anything particularly objectionable about any of it.
