3M and OverDrive don't run on
any ereader.
They run on Android devices though.

Even if that Android device is marketed for reading ebooks and comes with a default ereader app.
Some devices have connections via their parent company with OverDrive though. Which means you don't need an app or sideloading, because your checkout options include the option to redeem the book from the ereader manufacturer's ebookstore website and then download the book from your ereader's "Cloud"/"Archived Items".
Kindle does.
Kobo
should, because Rakuten, which owns Kobo, also owns OverDrive. But for some reason, they don't seem inclined to exploit that. Which is a shame.

I thought most European ebook consumers use EPUB-based ereaders, Kindle is supposed to be a lot less popular there.
But I agree it is extremely silly that public (tax-funded) libraries frequently lock out many people who already "paid" for their public library ebooks.

Of course, my US-centric rant is more about libraries moving to 3M because it is cheaper, when 3M doesn't support Kindle (only OverDrive does).
