A more generous interpretation: Intel made decisions that favored actual measurable performance today at the expensive of theoretically known vulnerabilities that might be exploited in some hypothetical future. They gave the market what the market demanded at a cost they tolerated.

And even now, after said theoretical vulnerabilities have been reified, there is very little cause to be concerned about the vulnerabilities under discussion unless you host code for other people as a business model (or use such a service). Otherwise your biggest concern is a web browser that already has a whole host of actual and theoretical vulnerabilities of its own.
