I've used most available services, but discontinued one after another along with promises that a better user experience will be provided with reduced content and removed functionality with the slight price hike. YouTube was my first and last video service I paid for, only Spotify remains on the borderline.
EEE and enshittification are very related concepts. The extinguish phase of EEE usually goes hand in hand with enshittification as once you've extinguished the competition you're free to cut costs and enjoy a monopoly. Cutting costs leads to enshittification.
Related in the sense that they're both common techniques in capitalism. You can use one without the other just fine. EEE can only be applied by market leaders, enshittification hits all (public) companies on the capitalist market.
