This way I use whatever free search engine for most searches (like when you type "steam" because you don't remember the url), and Kagi when I actually want more than the simplest first result.
However, if I'm paying for Kagi, it would be because I want to cut off using other search engines. Either I trust DDG and it's privacy and don't think theyre selling my data, and I continue using it, or I don't trust them quite enough (not accusing them of anything, I just don't know where they get their money from, and I know its not me paying them, so naturally just a bit worried), and I pay for Kagi instead, then I trust Kagi with all my data because I'm paying them to not share it. And in that scenario I've deemed DDG "not private enough", which would mean I dont want to keep giving them more info about me.
So in the end, I either keep not using it, or I want to make sure I have enough to cover everything. Which is probably just my own issue.
What did you mean with that that is where Kagi is headed anyways? Will you offer the unlimited package for a price which is a bit lighter on the wallet?
I too love to pay for things, and thus use a product, rather than be the product.
