Not speaking for multi, but, in any x-risk item (blowing up asteroids, stabilizing nuclear powers, global warming, catastrophic viral outbreak, climate change of whatever sort, FAI, whatever) for those working on the problem, there are degrees of realism:

"I am working on a project that may have massive effect on future society. While the chance that I specifically am a key person on the project are remote, given the fine minds at (Google/CDC/CIA/whatever), I still might be, and that's worth doing." - Probably sane, even if misguided.

"I am working on a project that may have massive effect on future society. I am the greatest mind in the field. Still, many other smart people are involved. The specific risk I am worried about may or not occur, but efforts to prevent its occurrence are valuable. There is some real possibility that I will the critical person on the project." - Possibly sane, even if misguided.

"I am working on a project that will save a near-infinite number of universes. In all likelihood, only I can achieve it. All of the people - even people perceived as having better credentials, intelligence, and ability - cannot do what I am doing. All critics of me are either ignorant, stupid, or irrational. If I die, the chance of multiverse collapse is radically increased; no one can do what I do. I don't care if other people view this as crazy, because they're crazy if they don't believe me." - Clinical diagnosis.

You're doing direct, substantial harm to your cause, because you and your views appear irrational. Those who hear about SIAI as the lead dog in this effort who are smart, have money, and are connected, will mostly conclude that this effort must not be worth anything.

I believe you had some language for Roko on the wisdom of damaging the cause in order to show off how smart you are.

I'm a little uncomfortable with the heat of my comment here, but other efforts have not been read the way I intended them by you (Others appeared to understand.) I am hopeful this is clear - and let me once again clarify that I had these views before multi's post. Before. Don't blame him again; blame me.

I'd like existential risk generally to be better received. In my opinion - and I may be wrong - you're actively hurting the cause.
