What even was the idea behind the original name? Was “Postmarket” meant to evoke aftermarket, as in an OS you install to replace the original OS that came with your device?

No, but it was a helluva lot more obvious what it was. I guess I understand their reasoning, but it's yet another obscure name among the innumerable ones out there already.

Have you read the article? If yes which aspects so you disagree with?

Edit: I don't want to change the original, but I didn't mean "did you read the article" as smart assert but as "is that a taste statement or something in relation to what they wrote?"

No? It wasn't? "The OS for your e-waste" isn't a good name for an OS this good. Also the old name was long, and with Google riling up FOSS advocates and annoying a good portion of normal users with their recent decisions, this is the perfect wave of criticism of Android and endorsement of alternatives to ride with some marketing.

I'd say the logo needs a redesign too.

edit: after reading the article, I think "Nurag" or "Nuragh" would've been better, but anything is better than the old name IMO.
