Kagi doesn’t hide that they use API calls to multiple sources for each search, they are fairly upfront about honestly. The benefits of use Jagi IME are the results are great, the site is fast and gets out of the way, it’s fairly affordable for what it provides, and the goals of the company is in line with mine (namely to find a thing I’m searching for). They are well funded enough to give me confidence that I’m not going to have to configure yet another search engine, and the integrate into pretty much all my access points easily as a default search engine.
I have seen no reason to think they abuse their position to impact my privacy, and bring closed source does not automatically make them evil. You included no alternatives that are open source, and the ones I explored were either difficult to get setup, required me to run something on my own infrastructure, or didn’t provide the integrations or results I expect. Kagi does.
Kagi isn’t perfect, and there are a ton of suggestions on their feature tracker that users rightly want implemented (including open sourcing more of their code-base). But as a paid search engine that makes me not the product, it does that job well.
Add in the congress critters from both houses need to run their own campaigns at some point, in many cases they can’t afford to just kiss the ring. This is especially true in the house where seats are up for grabs “soon” and the voter base is relatively small. If you’re a Representative and won your seat on a small margin, you clearly don’t have a mandate and need to act more moderate. Some senate seats are in the same boat (McCormick in PA, assuming the recount still favors him, is in this boat; he’s run three times now and barely beat out Casey this time, it’s a fair bet he doesn’t have solid footing for his first term and can only toe the party line so far). The only thing we should all bet on is at the end of the day everyone in politics is going to lookout for themselves first. It’s going to be a shitshow for at least the next two years, probably the full four and maybe beyond.
