The reason why you should learn Linux, or more broadly Unix is because if you're going to take software development seriously as a profession for 40+ years of your life you should have an actual well grounded understanding of how computing works. It's like asking, should you learn how to read sheet music if you want to become a musician, or should I learn Hanzi if I want to learn Chinese. Technically you can get away with not learning these things if you wanted to do the bare minimum but if you're gonna be even remotely serious about doing something as your craft just learn the things that underpin what you do. Learning how Unix systems work isn't just learning about a product, you're going to learn about file system paradigms, input/output, kernels, networking, address spaces and all the basics of CS that are everywhere.
