While true, that’s not the message here. While chromium is in a lot of things, browsers for everyday use (like banking etc.) is a huge part. You can’t control what services you rely on use as a basis for their software, but you can absolutely not use the software and/or opt for the website instead.
If you can reduce your exposure to that vulnerability by a large fraction by simply switching browsers with equivalent experience, it should absolutely be mentioned. In fact, it could even be seen as an obligation/core purpose of news outlets.
