Enterprise knows how to ask for money. They're always in your face. Open thunderbird and see what's the first thing you're greeted with.
Thunderbird asks afaik only once a year and they started very recently.
Also Thunderbird doesn't count as enterprise software.
Enterprise refers to distributions like RHEL, SUSE and similar projects.
Thunderbird's startup page asks for donations. Not saying it's a bad thing, but it's done right. How is it not enterprise and it's run by a corporation? Isn't Mozilla a corporation? Or is it not considered enterprise because it's free?
Enterprise does not mean it is owned by a corporation. Also I think Mozilla is a non profit but I might be wrong there.
Enterprise is about who the target user is. If it is designed to run on a single user desktop or whether its supposed to integrate into central management and authentication structures. Enterprise software is most of the time sold as part of a service agreement with the developer offering updates and support for special customer use cases.
Thunderbird is simply a universal mail client that can be used by anyone. Privately and in a corporate setting
I appreciate the detailed explanation. Did not know much of that. :)
Shit on Desktop Linux and its evangelists here
No evangelizing for Linux
