I think the issue is the clash with the image they have created in their marketing. These watches are marketed as adventure companions - Climbing mountains, diving in the ocean, etc, your trusty Tudor is right there with you. The marketing is all about building a relationship with the watch. It isn't just a tool watch, it is an adventure side-kick. Then they just swap out the "soul" every 5 years.
Once you get past the marketing, it's fine. It's just a mass produced watch. You wouldn't expect Swatch to service a movement and you shouldn't expect Tudor to, either.
