Which factor does NOT weaken competitive pressures from substitutes?

The factor that does not weaken competitive pressures from substitutes is price sensitivity towards substitute products. When consumers show high price sensitivity, they are more likely to switch to substitute products that offer comparable benefits at a lower cost. This dynamic enhances the competitive pressure as consumers may choose alternatives readily when they perceive them as being of equal value but at a more attractive price point.

On the other hand, factors like the availability of high-end performance products can strengthen a brand's position by differentiating it from substitutes that may not offer the same level of quality or performance, thereby reducing the pressure from those substitutes. Consumer detachment from brand quality indicates that consumers are less tied to specific brands, potentially making them more open to substitutes. The perception of quality among substitute products can also increase competitive pressures, as higher perceived quality in substitutes can lead consumers to consider these alternatives more seriously.

In summary, price sensitivity is a critical element that can enhance competitive pressure from substitutes, while the other options relate to aspects that can either differentiate or provide barriers to switching, thereby weakening the pressures from substitute products.
