I was shocked to see the browser market share graph. Chrome appears to be collapsing on itself, dropping from from an all-time high of 65.4% to 55.4% in just 16 months, effectively losing all share gains since 2016.

But then I looked closer at the data, noticing that only net 120 basis points of the change can be explained by share changes in the other browsers. The rest of the data seems to be missing, as the numbers add up to less than 100%.

What the heck is going on?

Edit: It goes without saying that the article's failure to address this point fundamentally discredits the author. It should be obvious that the first thing an article claiming monopoly would need to do is explain the plummeting market share of the thing that is allegedly a monopoly..
