"This reduced hash rate only applies to newly manufactured cards with the LHR identifier and not to cards already purchased." I think you got that, but just to be super clear that is the case. No need to be angry as far as I understand that's how chips are made nowadays. You can have wildly different consumer offerings on the same die. You buy 3 inflated balloons, seller takes five of them and while you are watching pops 2. "Did you really have to do that"? In chip manufacturing this makes a lot of sense. Your anger is basically towards a manufacturing process and naming not the end product. And the process is just highly optimized while naming keeps thing pretty transparent - it wouldn't look good if they tried to sell it as a completely new card.
