I just want to note that this is what is sometimes called carouseling. Which is, instead of acknowledging the original accusation was not correct, which is what should be happening, this comment just proceeds right on to the next accusation.
What is happening, psychologically speaking, that is causing a mass of people to spew one confidently wrong accusation after another? They don't have an endowment (they do!). Well they're not investing it! (they are). Well they're not working on the browser! (they shipped 12 major releases with thousands of patches per release with everything from new tab grouping and stacking to improved gpu performance to security fixes)
This is like a dancing sickness or something.
