I generally agree with your point, Mozilla is very much the odd one out being a non-profit browser vendor, but that last line is just weird. MacOS is a product

I generally agree with your point, Mozilla is very much the odd one out being a non-profit browser vendor, but that last line is just weird. MacOS is a product, not a company, and I don't think you can even buy it if you wanted, it just happens to come with the hardware you buy from the for-profit Apple company. MacOS also has nothing to do with Linux, except that they're both POSIX-y.
