On February 26th, Kindle customers will lose the ability to download eBook purchases directly to their PC. If you want to switch to a rival eReader brand in the future, I suggest that you use the soon-to-be discontinued “Download and Transfer via USB” feature to archive your Kindle library.
My solution was to just redownload all my books from z-lib after I bought them already.
I’ve been monkey paw’d with my wish “Z library becoming the most convenient eBook platform”
