Do they like the browser, or do they like the fact that it's not owned by Google?
When I use Firefox, either it's because I don't have a choice (my distro doesn't ship Chromium in a way I like, i.e. not Flatpak) or because I make an effort to "support" Firefox. But once in a while, I need to use Chrom(ium) because the website doesn't work on Firefox. Not that it is necessarily Firefox' fault, but the fact remains that if Chrome was an independent non-profit, I would most likely use Chrome and not Firefox.
