Yet it seems excusing corporate hypocrisy and inconsistency based on size and employee location to be par for the course.

Sorry, I'm not letting you get away with an illogical argument here. There's nothing hypocritical about the authors of web.dev making an auditing tool because some other people who work for the same company work on site that (may) do badly.

In fact, it wouldn't be hypocritical even if the authors of web.dev themselves worked on a site that did badly.

It is, after all, a tool. It's not a declaration of superior intellect. It's not an article of condescension. It's a tool.

The hypocritical statement is on the part of the company, not the specific authors. The efforts represent the company, as do their efforts in standards organizations, browser implementations, and email user interfaces. It is completely logical to question their inconsistencies especially as one of the primary drivers of standards. If the company cannot present a consistent front, we can ask ourselves whether their attempts to help others do so are accurate much less well intentioned. This should be obviously clear and not about individuals or their feelings.

Releasing a tool cannot be hypocritical. The existence of a tool to audit performance, accessibility, etc. is not a declaration of Google's moral or virtuous superiority. It's a tool.

Maybe the web.dev is trying to convince other teams at Google to improve their products.
