Source has been posted on Internet Archive (along with the latest builds for a bunch of platforms). Something will likely rise from the ashes of YuZu, but it wouldn’t surprise me if it takes a few years. Nintendo is probably gonna be extra litigious this year (even more than usual), due to them likely failing to have the Switch’s successor ready this year, and not really having a full slate of games ready, so with Switch sales projected to be down, best to lay low on anything that might get Nintendo’s attention for a while.
I still use DDG as my “daily driver” (I know there are better options for privacy and avoiding big tech, but I haven’t yet found anything independent that is good enough for me to switch to full time yet). I bookmarked Stract a while back, and it proved useful a few months back when Microsoft had an outage that took down Bing and by extension, Duck Duck Go. I do like Stract, their index seems to be enough larger than MoJeek (another independent search with their own index) that it gives me better results.
Stract might not be as open as I’d like, but it’s nice to have as an option, and I’m never going to complain about having more search providers with independent indexes.
