This article has attracted the obvious responses it wants to attract.
I bet many who've responded in agreement with the sentiment of this article use windows which is tied to a company that has done far worse than brave software.
Edit:
I am not sitting here for hour or more trying to figure out who is employed at a company of a piece of software I chose to use just to ensure their personal opinions, views and opinions align with current trends on what is sociably acceptable.
If we all were to apply this to all the software we use you will fast find out that you'll be looking for quite a few alternatives to what you assumed was neutral or aligned to your view point.
None of that is a reason not to make these things known. No one can escape from using brands that support something they disagree with. That doesn't lead to a conclusion that folks shouldn't make an informed decision on each of the products they do use. Part of that is going to be how hard it would be to give it up balanced against how strongly they feel about it.
Personally I dumped Windows in 2007 and each successive year has made me happier and happier with that decision. For other folks that's not a choice they can or are interested in making, nothing wrong with that.
In this particular case, Firefox is already my main browser, I have brave installed as a secondary only. It will cause me less heartburn to dump it than it did to type up this comment.
I just want the software I've chosen to work and do what I want it to well.
I'm not choosing software based on anything else as it's not part of my decision framework when making software choices. If it was where do you draw the line?
Do we only vet the C tier if not why not vet the Dev team as they are the people that actually create the product , Then the Q&A and R&D teams because without them the software would be more buggy and not have cutting edge features.
It's just a rabbit hole that's best avoided and for the most part I'd argue that 90% of people don't think or even care about the points raised because it's the last thing they think about when choosing a browser.
