The only times I've seen software (or other places) try to be "no politics" it was from clear fsscists wanting to avoid "woke" subjects.
Everything is political because everything is done through a context of society and the perceptions of the people behind it. When you deny that, you are just trying to shut down conversations about the ethics of things, and generally people with morals don't try to avoid talking about morals.
Also, religion and atheism are two unrelated things, since a religion is a social group and atheism is a personal belief. A proper comparison would be between, let's say, theists and atheists, and both are beliefs.
Moreover, it's quite a bad faith argument to compare beliefs, which are an unprovable, personal opinion, and things like software and politics, which are real world matters.
It's not the same to believe in god or not, or to believe that minorities need to die or not.
Overall, fuck off with your "not political" bulcrap.
