I've been a ddg user full time for 15+ years and I did see it improve quite lot over time. But quality dropped when Yandex was cut off.
Lately, I've noticed YET AGAIN being trapped in a bubble with results being to clever for their own good ... I did leave Google PRECISELY for the bubble effect ...
Not even mentioned the AI shenanigans with ridiculous results at times. DDG is not immune to enshitification. Way too many managers thinks they know better than the user ... they don't.
I don't think you can sell at loss in Europe (not sure, happy to be corrected), so might be small but it'll still be positive. The bet is it will be high enough to be a deterrent. The other bet is that at some point the rest of the world will push back being a corporate dumpster.
I get that it is particularly valuable in that scenario by treating other services as "external API", but monolith also do call "external API" and delegate work to async tasks. The principles discussed here API are interesting beyond just micro-services while being lighter and simpler than Durable Execution.
Don't bother. Moz management don't give a shit and haven't been giving a shit for a LONG time. It's like the f*cking magas, the more you tell them no, the more they double down ...
