Jerry,
In the past Gore has never pulled a license if a company used other products, only you could not say another product was better. However, it looks like they maybe handling eVent a little differently… perhaps they are worried about eVent. Who knows.
McDonald's does not allow the their franchisees to buy ANYTHING from another company. And that makes sense, McDonald's wants to make sure the delivered product is standardized.
Car companies cannot force a dealership not to sell another brand, but they can require the dealer to build a separate showroom for their product.
If a car breaks under warranty, the manufacturer REQUIRES the dealer to replace the defective part with an OEM part. Nothing wrong with that. However a car company cannot force the consumer to purchase maintenance items from them, if a competing product meets the OEM standards, as a condition of continued warranty coverage.
I don't care for GoreTex and haven't bought a GoreTex item in nearly 30 years. So I am not defending the product. What I am saying is that if a company does not like how GoreTex conducts business, then don't but the product. Let the market place determine the outcome. If Gore's licensing terms are illegal, then let the courts decide. No has to buy Gore products, they choose too. If a licensee feels Gore engages in poor business practices, then why on earth would they want to be a partner. Jump ship. Find an alternative.
