I'm sure it's not your intention, but calling them "Silicon Valley" companies seems to downplay the fact that one of them is the largest publicly traded company in the world by market cap, and another isn't too far behind. Instead if we rephrase it to "some of the largest / richest companies in the world" the jump in logic seems a little less enormous. I don't even know how to begin calculating this cost to your typical dev, so I couldn't say whether tens of thousands is or isn't in the ballpark, but I feel pretty secure in theorizing that there is an impact.
