Maybe it's just me,
But i don't get the complaints, you want the old situation? copy and pasting links, followed by slow and unresponsive? anubis is barely visible on this site and the least intrusive of the "prove you're not a bot" methods i've seen. no need to select traffic lights, cars or zebra crossings so you can help google in making their ai better at detecting stuff, no dragging things around, answer ridiculous questions or other annoying stuff. Of course you can try and ask your money back i guess.
The move for anubis is, i think, very sound and very defendable.
--Edit--
Sidenote: I also don't really get the "I lost my post" complaint, your browser has a "Back" button. when used it shows the typed message just as-is. no need to type again.
