Who cares ? Zuckerberg is a slimy rich guy who is NOT running for president. Donald Trump is a loose cannon who is dangerously close to becoming president. Zuckerberg appears to spend some of his own money on his own personal security. Trump uses demagoguery to run emotions high and divert attention from the fact that he has very little in the way of grasp of policy (or much of a platform). He says "look look here", and the media obliges and looks, looks there. This only started backfiring he head-scratchingly decided to force the Trump U lawsuit to the top of the news cycle.
It seems as though the original post is a thinly veiled attempt to paint Trump's critics as hypocrites. But there are many people who have serious concerns about Trump. There are so many people that don't like him that I'm sure one could find some hypocrites among their ranks. But let's step back from the distractions and take a look at what he has to offer.
