Talent comes and goes. If other companies can hire away talent, Intel can hire them back too. If you pay enough, people will come. Intel currently seem quite willing to pay.
It doesn't sound like Intel has been competetive on salaries for quite some time. Last time this came up, it sounded like Intel thought they could get away with Oregon salaries, meanwhile they're now competing with Cupertino salaries, among others. I suspect that they've had a captive audience for so long that they don't have a 'playbook' for a seller's market. All of the people who remember are either fat and happy or long gone.
Love of the work is one thing, but if you can love the same work somewhere else for 40% more you'd better think pretty hard about the wisdom of staying.
That's a change then. Before they use to aim for paying at about the 50th percentile. So Google and other companies would literally pay twice or more as much in salary in comparison.
