You need to develop some significant experience "collateral". Unfortunately your pattern of quitting is a red flag and while it doesn't exclude you it means anybody in a hiring position needs to see positive evidence that you can actually contribute in a serious, long term manner. Either an unsexy job coding (short term contract work, etc) - or - seriously beef up your open source (github, gitlab etc) portfolio with some really top notch contributions and ideally some projects of your own. Also - I know this might be controversial, but drop the fsf email at least for your job applications. I'm a huge fan of FSF but I can tell you it's also flagging you as a potential over-zealous, opinionated person and all things being equal someone equivalent who seems pragmatic without that is going to get the job.
