Yes. I use Brave Search and I hope they add a paid tier, which I think they have confirmed they'll add at a later date.

If you don't pay, you are the product. Simple as that.

I would - the problem with those services is that they prioritise the results that generate the search engine the most money rather than give me the best results, and then indexes my searches to track and advertise to me throughout the web.

A clear pricing transaction sounds much nicer to me. Should generate better results too.
