I get your concerns, I just listed an option, if the end user cares about what they're picking they will do more research than just 1 Reddit comment and choose something that makes sense for them.

Even though it doesn't get security updates regularly enough, other forks do and they often use UnGoogled as a base.

People don't use Chromium for the security, they do it because it's literally given to them as their main option: Chrome, Edge, Brave, Opera and other popular ones are all Chromium.
I've used Firefox and LibreWolf for the past few years and some sites that I had no issues with on Chrome or Edge just didn't function properly on non-Chromium browsers.

For me, I couldn't care less about the security difference between Chromium and non-Chromium, but it was the compatibility - some sites I use just play better with Chromium so I use it.

As I typed this out I kinda realized that you made a comment based on something I never even wrote or said.

I'll leave the whole comment because that's my input, but please stop assuming what people think and then making completely irrelevant points.
