@Uplink10, I think that is more a default for the segment... If it is not then it should.
They want to remove the warranty from you by any way they can (less warranty = more profit). Which may seem evil but I think the manufacturers are more a victim than anything, why? -> I am tired to see users who bought the product and damaged them by incompetence, lack of prudence, care and much more... And activated the warranty to replace the "intentionally" damaged product for a new one for free by lying and being dishonest.
I would be surprised if ordinary computers and tablets, for example, did not have the same rules to follow (unsupported OS = warranty void).
But that is certainly not a good thing for those who rely on warranty... But those who do tries to follow all the rules and are aware of what they can do or not.
That is what I see in my country, yours may be different or not.
Just my opinion.
