I cannot understand why anyone would be so childish. It’s not even as though money is involved; it’s some kind of juvenile popularity contest by people who clearly don’t believe their work speaks for itself, and clearly don’t take pride in their product.
Manjaro defaults to a defective dock that is riddled with bugs if you customize it. I broke it dozens of times just by making some minor modifications in the preferences. It also slows down a little gradually. That’s only minor but the dock thing really irked me. Really? Can’t just get the dock settings finished so the thing completely works? Anyway, that was a few years ago and I haven’t touched it since.
