Future Kobo book purchases and removing DRM

So I bought my first Kobo book today (as a Kindle user, but not wanting to spend any more money on Kindle books)

I followed the tutorial here, specifically for "those without a Kobo device"

https://www.reddit.com/r/Calibre/comments/1ck4w8e/2024_guide_on_removing_drm_from_kobo_kindle_ebooks/

Everything went fine, I used the Kobo desktop app for purchase, and Obok plugin, converted in Calibre and then sent the Epub to my Kindle. No issues

My question is, when you open the Kobo desktop app you get a warning "soon you'll need to make your purchases on kobo.com". I read that to mean the Desktop app will be useless at that point, at least for purchasing.

Does anyone know what that change would mean for non-Kobo users, as far as removing DRM and getting them on a Kindle?
