First of all, a lot of carpenters do in fact work on side projects in their free time. My dad certainly does.

We need to recognize that programming is a creative craft and the norm for those is to do it as a hobby.

Most musicians, including "professional" ones, play for fun as well. As do dancers, poets, writers, artists, etc.

Do you think most academics leave "work," go home and never think about their research again?

I have no problem with people who somehow decided to program despite not enjoying it enough to do it in their free time. But they shouldn't attack those of us who do for daring to spend our free time in a pleasurable way. And they should accept that there's a simple reality that those of us who enjoy it are going to spend more time at it and thus level up more quickly.
