Louis Rossmann (1.7m subscribers) ascribing his decision to leave GrapheneOS directly to the behaviour of Daniel Micay and stating that "he will never feel comfortable running this code on my phone as long as this person is involved in it" probably began triggering real calculations within the team as to what extent he was slowly becoming more of a liability to the project than an asset. Although, it's unlikely Louis saying that was going to affect the project in any meaningful way, this is not the kind of commentary that makes your position more tenable. I'm glad Daniel pre-empted those conversations by taking the decision to step away himself.
There is no doubt in my mind that Daniel Micay has been subjected to systematic harassment campaigns, far exceeding those of a typical open-source developer of his stature. That kind of stuff has an impact on you and as a result you behave in a less reasonable manner (i.e. more paranoid, less trusting). I just hope the dude takes a long break, gets buff and comes back stronger.
