Since here the answers are split between edgy kids and people repeating a bland, stale narrative about comfort and fear of death, I will try to bring a different perspective.
For context: I grew up in a Catholic country but in a very secular family and in a very secular region. I've had an edgy atheist phase that lasted between 8yo and probably around 30yo.
I studied a STEM discipline and have always been surrounded by mostly atheist or agnostic people.
I was afraid of death up until I was 27/28yo, but the cope was gnostic transhumanism, not Abrahamitic religions. At some point I took acid, my gf at the time told me I was going to die, I cried my eyes out for a few minutes and then I was fine and I'm still fine. I had a near-death experience in the hospital that further consolidated the idea that I'm going to die, and it's chill: if you're sick, you have a bunch of people looking after you, everybody gives you attention, you spend all your day chilling in bed on drugs. Dream ~~life~~ death.
I was still agnostic at that point. I started approaching spirituality later on, not much because of an emotional need, but because further studies both in STEM disciplines and Philosophy highlighted the limit of reason to explain and understand the world. Reason is a tool among others, with its limits. Limits that can be reasoned about using reason itself. You cannot investigate or explain what lies outside though, let alone change it, something for which you need different tools: faith, spirituality, trust. I got closer to what Erik Davis calls "Cyborg Spiritualism", but it doesn't mean much since it's not an organized movement, but more of a shared intuition and meaning-making process to which, in the last 60 years, more and more people arrived. Especially people dealing with disciplines like system theory, cybernetics, system design, and information theory, but also people disillusioned with the New Age movement or other Western Gnostic practices. Mixed in it there's plenty of animism.
Atheists believe that all religions are about speaking to God, and hoping for an answer, while many religions are about listening to God because they are already talking to us all the time.
A lot of coopyleft or p2pp projects adopt the license and it's not discussed that much in the identity of the project.
I personally believe that software freedom shouldn't come at the expense of people's freedom, and I consider the FOSS movement a political failure because it's completely incapable of mediating between the two things. New generations are growing more and more alienated from a movement they consider a relic of the past.
For my projects, I avoid FOSS licenses, but they are also not relevant enough to get insights from them.
