I use Brave Search because it's the only that gives decent results hassle-free to Tor users. Google still provides the best results for normie topics, and acceptable ways of accessing them are Startpage, Searx, and GPrivate. Although those may not be relevant if you're seeking to boycott companies. There's also Seeks (which is different from Searx) and YaCy, but you have to set them up by yourself. Another good metasearch engine is Dogpile.
