To this date I can still buy broken Intel CPUs....
They knew about the flaw in June. Yet they still kept selling Coffee Lake CPUs.
If my 8700k wouldn't still be significantly faster than Amd Ryzen (or I wouldn't have to also return the MB), I would have switched to an Amd in a heart beat.
With this they need to add even more tests before they can start on attacking the issues with the design.
It's understandable that they may not have been able to mitigate it in the 8th gen CPUs in just a few months, but they also put those CPUs out on the market, advertised them, and sold them, all the while they knew of their design flaw, without saying anything about it to the unsuspecting customer.
Moreover it would be hard to say "everyone is doing it" because it seems so far besides the latest ARM processors, most of the other CPU architectures don't do it.

That was in 2005. It might be an over-generalization, but one could say that Intel made that same mistake (at least) twice.
I don't see how a class action could apply here, by IANAL
