There are some benefits in some circumstances, but a lot of people who use linux do so not because of any tangible benefit, but because they support open source, and don't like the idea of one (arguably a couple) big corporation having a monopoly of that magnitude and deciding alone the way tech should evolve.

Speaking for myself, I'm from a developing country, and I mostly use dated tech, some of which don't even support windows anymore, and it gives me the possibility of extending the lifespan of my stuff. This is the main tangible benefit for me.
