I've dedicated 4 years of my time and money to build and maintain ColdCast with the aim of creating a space that respects privacy and freedom of speech. I recently expressed the need for support from the community to keep ColdCast alive, and regrettably, very few of you responded.
That said, it gives me great pleasure to announce the shutdown of ColdCast. It's not worth my time anymore. If you are in need of an alternative free-speech platform, you can use PostPile.
