I don’t want to sound like I’m on Discord’s side (I dislike nitro too), but that’s honestly just how a lot of paid add-on features on free apps work. They take away some functionality from the free one to incentivize people to pay.

I can tell when there are electronics turned on around me even if they aren’t intended to make noise, because they all seem to give off this kind of almost imperceptible high pitch whine.

I can also hear the noise that some batteries make when they get charged.

I believe the English one is the original. The “original” one (the one in Chinese) was probably translated from English.
