I don't think you can download ebooks from the Kindle store and transfer them to a Kobo unless they happen to be specifically DRM-free ebooks (which very few ebooks are, and basically none from the big publishing firms)? And even then a format conversion would be involved.

(If you mean transferring them to the Kindle reader, you can of course download the books directly on-device.)

You can remove the DRM pretty easily, which is likely why Amazon is making this change.

It's getting harder. Calibre + DeDRM doesn't work on all kindle books, especially some of the newer formats.
