Its not free or open software, so using it is a step back.
In its original form, free and open is noble. But since then, corporations have figured out how to monetise it. So, IMHO, we need to be very careful about anything free and open coming from corporations because their core objectives are very much orthogonal to the core objectives of the original free and open software movement. Those execs aren't the hackers who built the gnu/Linux tools in the early days.
I use qutebrowser, vivaldi and brave (on mobile) and sometimes console based browsers when I can get away with it. Qutebrowser and Lynx are open source. Vivaldi and I think Brave aren't open source? I'm using them because I read about their team, their business model, their past and hung out in their forums and decided that I'd support them. Doesn't mean anyone else have to. And there's nothing wrong with making money off opensource software and that's how it was intended in the first place. Original open source software authors didn't mean that the software has to be free of charge. For me, I don't want to support an organisation that sacks the researchers of their core product but the execs pay themselves millions of dollars. Most of those dollars come from Google. I'm sorry that that makes no logical sense to you.
