Like so many things, this has beecome political. So, folks will often do whatever Biden recommends or suggests, or the exact opposite.
Whatever Biden says doesn't mean a thing to me, nor what Trump says or said, about a technical topic. It's akin to the climate change story, which really shouldn't be political but obviously is. I think this will happen every time some technical issue gets in front of the public who will make a decision based on politics, rather than science.
