Ya I'm not surprised. They openly came out and said their future goal was to become a public company. They are building for big corporate money and that means they will harvest and sell your data and other typical things.
It's just a copy of Twitter and their goals and plans are exactly like twitter. They will manipulate and shape the narrative based on whoever has big money.
I don't like that app. It's identical to twitter. It's ugly.
I will continue using Amethyst.
