I don't get why they did this, Ark is such a great resource. If there is any cost to keeping the data usable, surely it can't be that much worse for ultra-legacy products that it only makes sense to keep around "newer" (and I use that term very generously) products.
You know they've got at least 10x the server cost being wasted by old emails and stuff like that which could be more sensibly purged instead of customer reference documents.
Perhaps it's an anti-recycling effort against those who would otherwise keep running these old processors which once played a respectable key part in Intel's progress.
After digital files first became available for electronic components, there has never been any good excuse for them to go out-of-print after that.
If it isn't just some error
Turns out like every corporation, they have both sides.
Second, for compilers you have projects like LLVM that's like a framework for building compilers where those companies like Intel, AMD, Samsung, etc contribute.
LLVM shouldn't turn into compiler monoculture.
