oh yeah, I'm aware of that. That's why I find it odd to just see it handwaved as a 'driver fix'. It goes well beyond the accepted norm for a driver fix and more like a post-release firmware flash without the bad press that that would generate.
The stock boost was altered, not the factory overclock boost. Boost clocks are a part of the stock performance of the item and how they are marketed and sold. Look at the issues AMD ran into with the boost behaviour of the 3000 series, inc threatened lawsuits over advertising/sale information.
Whether it causes issues or not to current owners is irrelevant. It's a post-release alteration of the power scheme of the board, something that features heavily in reviews and indirectly affects other performance metrics due to how integral boost behaviours work on modern chips. If Intel sold you a SC boost 5Ghz 100TDP Processor and then released a stability patch that dropped your boost to 4.9Ghz and raised your TDP to 110 two weeks after launch, you have been mis-sold and it is not the modern 'normal' thing to happen or standard practice, or as simple a thing as 'a driver fix'.
