Because that logic is the same of the drunk looking for his car keys under the street light, rather than the dark area were he lost them. AMD's server market share is minuscule and dropped as of 19Q1, 3.2% to 2.9%, although healthier and growing smartly in desktops and notebooks, up to 17.1% and 13.1% as of last quarter (I would guess the two are related if the comments made in this discussion about their being fab capacity limited are correct). That means they're less significant targets for researchers than Intel and ARM. We might also assume AMD has less manpower to devote to finding vulnerabilities than Intel has. These latest Intel vulnerabilities, Foreshadow/L1TF and this week's? They're all targeting Intel specific details, for example the first Foreshadow version targets the SGX enclave.

The odds that AMD specific features have vulnerabilities than simply haven't been looked for yet is very high, their Spectre vulnerabilities show that they too generally got caught with their pants down.
