I also agree that Kobo does not care. There are so many bugs that people complain about and in each new firmware that they release, we hope it fixes them. But no, bugs are still there. I have even contacted Kobo support about pdf book problems probably approx. a month ago that there are bugs (since fw 2.8.x) in landscape mode. They promised to send it to developers to fix it but what we can't see are fixes. Bugs still there.
Kobo is like Nokia in its old days when it was said: "once everything works what you use in your phone, don't upgrade FW because it probably brakes it." Meaning every new update that fix some issues brings new bugs in things that worked before
