True, but it is insanely slow, and blacklisted by many websites.

Nah, seems to be a different meaning, and I think it probably has to do with dot files as other comments have mentioned. Also rice burner and other terms seems to have been used directly in conjunction with Asians, to insult products made by them or the people themselves. As Unix is not really a Asian product so to speak, I doubt they’re related too much, and if so only tangentially.

I would say there’s an argument to be made against duckduckgo with how they’re not open source, and the whole allowing Microsoft trackers deal, but it is definitely a better option than google or bing. I don’t understand why you’re mentioning their browser however, as there are definitely much better alternatives.
