as long as AMD keeps lying about how the meltdown and Spectre threats affect them then this will happen
Why are you worried about this? If they're lying, they get exposed and it'll be even worse for them. AMD is doing fine - they don't need to lie, and it'll only come back to bite them. Moreover, AMD can't afford to burn any trust with the lucrative data center customers they're courting.
Google has implemented the exploits, and will surely tested them against all products, going forward. If products remain insecure, they will publicly disclose that.
Increasing gpu production is meaningless for the end user. Because video cards are zero effort money making products, demand is pretty much infinite. No matter how many are produced farmers will buy them all. The more they buy, the more money they generate to buy more cards. The only scenario that will reduce demand is a tanking in currency value making it unprofitable to use GPU's.
