Yes, regular customers will stop buying. But diehard fanboys are still going to buy it. OnePlus has built a huge fanbase here in India over the years with the help of it's Competitive pricing & Oxygen OS. Even if they launch their next phone at ₹70k, those fanboys will still blindly support it. This leads to brands to take advantage and exploit that fanbase.
Fanboyism has become very toxic. I hate to read the comments on tech related tweets now. It's all about defaming other brands and claiming that the one they own is the best.
