I had to track this back a while to figure out what point was being made, not entirely clear but it seems tied to social media being controlled by "the left."
That may or may not be true, but this data proves nothing. It's penny-ante stuff, a record of individual contributions of employees who could be anyone from a CFO to a mail room clerk, totaling (according to the article) $2.4 million from Facebook employees and $347,000 from Twitter employees. And no indication that these people have any particular management influence. Peter Thiel alone donates more than that to conservatives every few weeks.
