Proprietary Software is Not a Luxury
Luxuries can come in many shapes and forms. They try to sell us an "experience" or some "ambiance". They typically assert to be "the best" even if they're almost the same and mostly indistinguishable, e.g. a little more leg room in the plane (for a passenger who pays 3-4 times the "normal" fare, which they call "coach" or "standard" so that they can upsell stuff as "business" or "first class"). We see this in the food industry ("cuisine" or "gourmet"), in the fashion industry, and also in the software industry.
Alcohol is bad for internal organs (and the brain) no matter the "brand".
Fashion (typically clothing, garments) is made in sweatshops in southern Asia, irrespective of the "label".
When it comes to proprietary software, it tends to come with a higher price tags, sometimes more bells and whistles. But it contains a lot of bugs, those bugs don't tend to be fixed (sometimes they charge for new versions that tackle bugs), and in most cases there's bloat and a growing risk that the maintaining company - not a community but a single point of failure - will go out of business.
Proprietary software is not a Luxury. It is a liability. █
