Leave it, he doesn't want to understand so nobody can make him understand. This is a perfect example of this saying:In case you don't know, BBK owns oppo, vivo, Oneplus, realme & iQoo. They have 40%+ market share in India.
Similarly, I assume there are 10+ desktop GPU makers, according to you? There are just 3, Nvidia, AMD & Intel.
Those who want to believe, no proof is necessary. Those who don't, no evidence is sufficient.
