Intel sold so many processors those last years, that it would totally destroy them any meaningful compensation. Considering that AMD can't support the whole planet with Ryzen processors, neither ARM architecture can replace x86 in one night, the only option probably is a discount to anyone who can prove that is still using an affected by Meltdown Intel CPU today. And that discount should be valid also for everyone buying an Intel 9000 tomorrow, because even that processor would be probably affected. If it is not, then either Intel enginnears are magicians, or all these security problems with Intel processors lately, are not a coincidence.
Spectre affects everyone so, I don't know if companies should compensate their customers because of it. Most doors in the market can be opened by thieves, even when they are advertised as secure doors. We never seek for compensations for something that affects all products in a certain category. We just accept it as it is.
