you might want to read up on the controversies surrounding him first though

From the sibling comments, it seems like you're just referring to his history of abrasive social interactions on bug tickets. Granted it is strikingly abrasive, but that really isn't a good reason to forego donating. At the very least don't actively convince others not to donate.

Do you mean because he's arrogant? Who cares? The software is great and saves me a ton of time and money.

I care. As developers we have the moral responsibility of not putting people at risk even if we don't have the legal one.

The author has zero care for security and the product had plenty of vulnerabilities. This harms users and also other people.

Furthermore, poor behaviors attracts blame on the whole open source community.

If you're referring to the "I'll personally maintain Python 2 if it goes EOL" comment, Calibre has been slowly upgrading to Python 3.

[GrayShade]

It hasn't been upgrading to Python 3 by itself but through the effort of a distro maintainer and other contributors: https://github.com/kovidgoyal/calibre/pulls?q=is%3Apr+author....

You might want to add some specifics and references to back up such a statement. Otherwise it very much looks like a fairly cheap character attack to an outsider such as myself.

I would argue its always better if people form their own opinions, so I just suggested that people should look it up themselves and come to their own conclusions.
