What I don't see is where Brave gets its image search results from. After Microsoft blatantly started serving the CCP by blocking queries for "tank man", which as far as I know they've never actually apologised for, just explained it as "a filter with more impact than expected" or some BS like that, I found out that most "competing" search engines bought all of their image search from Microsoft, leading to the same kind of censorship on platforms such as duckduckgo.
Brave says it's using "third parties" to generate the results but I can't easily see which third party that would be. If they are using Bing like all the others, I wouldn't trust their image search engine in the slightest.
Personally, I'll just assume they are for now, because they don't seem to clarify this further anywhere else.
From what I can tell, there are four image/video search providers in the world: Google, Bing, Yandex and Baidu. The rest all seem to license their results from one of the big four, mostly from Bing. When I need to pick from those four, I'll stick with Google; their censorship is relatively mild. I was hoping Brave Search would prove to be an alternative in this area, but that doesn't seem to be the case.
