Discrimination and not making a product that needs a seperate production chain and has a much much smaller potential client base are two different things
No, no, and no. And for several reasons.
First, do you have idea, how many different designs Logitech manufactures? Hundreds. Yet NOT A SINGLE ONE OF THEM is left-handed.
Also argument about low-revenue and small client base is so wrong, I have trouble comprehending it.
Bit of background: for hundreds of years, left-handed people were oppressed, for example my mom, born in 50s, had received corporal punishments for writing with her left hand in the school, by being hit with a wooden pen-box, and had her palm bones shattered in the process. So was my sister, born in 70s, but not in such gruesome manner, thank goodness. I've been born in 80s, and I was left alone only because I had bitten to the blood every teacher that tried to force me write with right hand. Only in the 90s stigma has been lifted somewhat, but I still hear sometimes a woman being angry at her kid for being a leftie. Surveys done in 70s and 80s show that close 10% of population is left handed - while it was oppressed. Today, when no-one cares, it's being estimated closer to 20%. So 1/6th or 1/5th of humankind may be left handed. No client base? Please. Currently there is literally single left-handed mouse on the market, Razer Death Adder - and for a good reason people are not buying it, because Razer is famous for manufacturing crap. Quality mice would sell like hot cookies, there is simply no comptetition.
Argument about low-volume production is also moot, since Logitech makes 3D presentation controllers and ring mice and trackballs, with production volume in hundreds per year. So even if they manufactured little run, only problem would they face would be thousands of mail asking, where there will be more coming.
You're worried for revenue? I'd pay 300$ for left-handed mouse, even if it had mediocre sensor, flimsy cable and two buttons. This is not a joke, I mean it. Lots of us would.
Left-handers have earned much enmity for being vocal on this issue, and I suspect many have given up and use ambidextrous mice, and it's just sad. I once received high-end right-handed, profiled mouse as a gift, and to be hones, I felt humiliated, when I had to sell - there was no point leaving it on the shelf, collecting dust. The person that made the gift, simply doesn't understand me on this day, and we, in fact, ceased to be friends.
