To me as an end consumer, Facebook has a true monopoly and progressively shittier products compared to Google - ads comprising half of my feed, their core product is still broken and buggy in many places but that's another topic. Recent UI changes made it much worse product. Google looks great compared. But again that's very personal and limited view.
