I'm also unsure about protest banners, but on the general theme of holding your fire, "this is exactly how big companies lose against startups. They wait around to see what the startup will do, and by the time they have figured out that it’s important it is too late to catch up. This is why Andy Grove’s motto at Intel was “Only the paranoid survive.” So working with startups has taught me: don’t wait until it is too late. Protest early and often. We wouldn’t even be here if people hadn’t grossly underestimated Trump to begin with." (From Albert Wengler earlier this week, http://continuations.com/post/156262260395/what-i-learned-fr...)
