(ex-Googler, spent 18 yrs there)
Memegen is a key part of the culture. Its default mode is over-the-top mocking, of course, with a grain of truth. Nobody and nothing is spared. C-level execs, products, the perf process.
So this by itself is not quite the scoop 404 media thinks it is. You could take the front page of memegen on any given day and construct twenty scandalous headlines of it.
Came here to say that (not a Xoogler, but very familiar with portions of Google). Other companies have similar things :)
On top of what you wrote, Memegen is not representative of opinions among Googlers. Memegen, like most social media, focuses on the extremes. You'll see a lot of spicy takes, but that's not what the typical Googler thinks. For a more realistic view, the comments on Memegen are better but, again, unlikely to represent the views of most Googlers.
So this article boils down to "On a site that focuses on extreme positions drawn from a very large population of people, we found extreme positions about this product." Doesn't really tell you much about the product or the very large population. You can make the same statement about most products and most very large populations.
