An exception to the rule is Xiph Cyber (https://xiphcyber.com/). They've been making donations to GrapheneOS based on a portion of each phone they sell for years.
Some of the companies building on our work are upset that we've made it easier to install GrapheneOS and gradually obsoleted their changes.
@grapheneos to be honest GrapheneOS has never felt so alive to me. With new features, cleanups, etc, I couldn't be more grateful for your work. If I weren't a student, I would certainly donate more :)
Keep it up with the good stuff!
