I’m guessing all of Google’s internal apps are only tested on Chrome, with plenty of Chrome extensions, which means that all of the developers have to use Chrome to make the tools work, and at that point, switching back and forth between different browsers is a pain so none of the other browsers get the love they deserve.

The attitude of “it works on Chrome, I don’t care about anything else” is fairly widespread anyway. Just to stem the tide a little bit I’ve been developing on Firefox and Safari first, and then checking Chrome last.

I got bitten before when I made a browser game, and then noticed that it was all sorts of broken on Edge, even though Edge supposedly had all the features I needed. It turns out that Edge did have all the features I needed, but I had accidentally used a bunch of Chrome features I didn’t need. The easy way out is to turn things off when I detect Edge. The hard way is to find all the broken parts and fix them. So nowadays, I don’t do any web development in Chrome.

Considering that there's been an internal and external bug filed about the US states not being in alphabetical order on contacts.google.com for years, making it impossible to type 'new y' to get New York, I don't think raising it as an issue will help much.

It's easier to change the thing you're in charge of than it is to make a new company-wide policy.

In large corporations politics are abound. If the Chrome division cannot get other divisions to behave through other means, this is fine.

You can see that they should have fought harder and escalated, but issues like this are probably not the ones most upper-middle management want to potentially damage their career for.
