These days with Android roms, it's not so much what you're doing publicly that I care the most about, it's who and what your company is and who's funding it.
I'm iffy on /e/os and Murena, and I'm equally iffy on you until proven otherwise. There's a lot of actors in this scene and it's hard to tell at first glance who's really in it for privacy and security and who's just here to bankroll users into their ecosystem.
but!
From what I can see on your site, at least from first glance, you all seem to have good intentions... for now, anyway.
They're a bait and switch into their own services. I suspect Murena has more intentions of profiting from the FOSS community than contributing to it.
Murena is a public, for-profit company. You could say that's nothing to worry about for a company and CEO with seemingly benign intentions, but the same could be said for OpenAI way back when as well.
And, like Graphene and Lineage, they're a band aid on a bigger problem, Android. These companies would all do the world better by donating and contributing to mobile Linux, either devices or software.
