By default this is because the skill bell curve in programmers including their managers. Most developers simply don't really care too much about their profession. They use what they've been taught at university or whats already used at $CORP job, fulfil some requirements given to them, and collect their paycheck. They usuallt can't be bothered to pick up more interesting tools on the side. Ontop of that there is fluctuation and risk-avoidance, so using anything that is not absolutely mainstream is seen risky, because replacements might be a bit harder to get. Combine that with the usual mediocre preexisting employee base, and its obvious why by default the dumbest/broadest thing is everywhere in use, even though most people involved in the decisions aren't idiots. There are roughly 2 types of places where you can encounter Elixir or other exotic tech: 1. The decision maker / CTO / tech lead actually has the autonomy and the personal interest in this tech so he is the driving force to level up and stand out. Only works in tandem with enough dev motivation in the team or it will backfire. 2. Startups/new tech insourcing departments, where a small circle of actually competent/motivated people got to choose the foundation and are by some miracle not blindsided already with "pick the cheapest and least risky" option but understand that tech can be the critical advantage needed. Joker slot: be a solopreneur and use whatever you feel comfortable with. Thats the general escape hatch that is becoming increasingly popular it seems.
