FUTO made a $40k donation to GrapheneOS supposedly with no strings attached. They ended up being unhappy with us not making content with them and promoting them. They began supporting attacks on us and tried to destroy the GrapheneOS project. Recommend not taking money from them.
FUTO apps aren't open source but rather source available with heavy restrictions on usage:

They're taking the place of real open source apps and making it less likely for viable options to emerge since people are going to use and contribute to these.
Discussion
It's not hyperbole to say that FUTO has caused millions of dollars of damage to GrapheneOS with the fabrications and spin they're still actively spreading about us. Any developer offered money by them should be aware of what happens if you don't promote them and tolerate abuse.
Damn, I was just starting to enjoy their keyboard.... any other suggestions? stock AOSP KB is painful.
