The lesson here is that it's important to "sell" new versions of anything. You can't just expect people are going to upgrade because it's the new hotness. Older versions of your own software are often your biggest competitor. (See also: Microsoft and Windows 8).

I think that's also a lesson for the people who are unhappy with the changes. People grumble quietly and just decide not to use the new versions, so the devs have no idea how many people like or dislike each change.

I didn't find it simple to google for what the differences are between 2 and 3. As an outsider to the Python community, that would be very important information to me if I wanted to learn the language. The most immediate answers I got was "use 3 because it's the future".

I don't know what you mean by "I didn't find it simple ....". I googled "python 2 und 3 differences", and that was the first result.
