No, it's objectively not worse, you can compile Chromium yourself and remove any features you don't want, something you were never able to do with IE.

Chrome != Chromium. The vast majority of the planet is using Chrome, not Chromium. Most average joes have no idea about Chromium.

Either way, whether you're using Chromium or Chrome, you're still entrenching Google's monopoly over the web.

Like the sibling said, the problem was IE's monopoly itself not the lack of more IE-based variants which wouldn't have helped at all, the same way how Chromium isn't helping counter Google's monopoly.

I don't think not having enough versions of IE was ever a problem. The problem starts when everyone builds their app to a platform that is very dominant and controlled by people who's interest are not always aligned with the user's interests.

You don't have to compile Chromium to have a browser incompatible with the websites that people build for Chrome, you can just use Firefox or Safari or write your own browser if you want to have a web browser that won't be able to run Microsoft Teams.
