Intel tampered with information security for 30 years? Yes, they (or at least some of them) had known that speculative execution causes security problems. But no, they have not been in business that long with technology that could be affected. And more importantly the whole industry is too young to have any security regulations. Very much like the car industry in the 1930s had nothing comparable to today's safety regulations.
