I have a hard time thinking of a "bad" Apple product. Not "product I don't personally like" or "product that fails to meet a requirement I believe is important", but legitimately "bad".
The Butterly keyboard is the only thing I can think is genuinely, objectively, "bad", due to the reliability issues, but it's hard to say it taints the whole MacBook Pro. I use one everyday, have since they were released, and it's a great laptop for me.
Either way, I'm mostly commenting on the ever-popular and lazy comment that equates Apple's success solely to marketing. Apple's products are successful because they're good products, marketed well. Yes, they're marketed well, but that marketing is only effective because the products being marketed are genuinely "good".
Some are good. I’m not an Apple hater. I have an older (good model) MacBook Pro, an iPad mini 2, an iPhone SE, and an iPad. (All with connectors such as headphone jacks)
It’s some of the newer models that strip off functionality for aesthetics , or at least slimness at any and all costs, that turn many of us away.
I guess AirPods work for some, but I wouldn’t touch them.
