I hate this take. Everytime Calibre is posted on HN, someone always brings up Kovid and complains about how the software isn't up to their standards. Then everyone circlejerks about the ways Kovid has incensed them in some way or some form by posting some comment on the internet. Imagine maintaining a 500K LOC application for free and for almost a decade, and being criticized by people for using a legacy language. Especially since no other application comes close to the functionality Calibre does.

Calibre has been completely reliable on the multiple e-readers and computers I've used it on.

The only reason this migration is taking place because out of the thousands of people on this forum who complain about his code, several of them decided to help him instead of continuously complain.
