I haven’t checked this week (yay, might already be too late) but my understanding is that amazon only disabled the web interface to download ebooks to a computer.

Using the (Windows) Kindle for PC App at a sufficiently old version was still working last week even after people had claimed the web interface was disabled.

It is only a matter of time but it is also something that the vast majority of people are too computer illiterate to do so it is probably going to be a decent amount of time. Cost amazon more to disable it than to let people do it.
