The status quo is easy, change is hard, and anyone benefiting from the status quo will do whatever they have to in order to prevent change. Progressive by definition want change, progress. Change is scary. Humans are most easily motivated by fear.

I think it's a little more than just fear of change. Garry Tan knows where his (material) interests lie, and will do and say anything to fight off those who would build a more equal society, even if it means supporting actual fascists like Trump. The ultra-wealthy are very class conscious.
