Angor is decentralised, the founders have explicitly designed the platform with this goal (deplatforming) in mind Granted (!) it's more geared towards a more serious raise, with milestones and on-chain transactions We used it to claim our @SIGit award and the process was smooth. Disclaimer - we've supported Angor in building their product. Catallax looks great, I wonder if it could become a standard for donations
