What's sad about using products that work?
You are believing a company that says only wax darkens leather when we all know different? The reality is that wax can be seen longer(darkens leather) because it doesn't soak in and fade out as quickly as plain oils would. And why it works better as a water repellant than plain oils or surface type protectants.
I tend never believe a manufacturers claims about their competitions products nor about their own. Leather needs oils to maintain them, and they darken leather in doing so, it cant be helped. I would instead worry about those products that don't darken leather as they really aren't doing much IMO.
Some more food for thought not all leather needs the same conditioner or oils, each leather product has its specific use which really determines the type of conditioners needed to protect it to the fullest.
oil is a natural product just not renewable in our short lifetimes. We will be in the next batch!!. Many leather workers have been scared by the big bad eco bullies because they are either to lazy to find the truth or just want to remain willfully ignorant and virtue signal at every intersection. Petroleum products work and work well that's why we invented the processes that refine them. BTW The whales were very thankful for the creation of kerosene!!!
