In the 1980s, I remember plotting the results of science experiments in high school on millimeter paper. Logarithmic scales came in handy: they allow you to plot data series with big variabilities accurately, and/or they can show mathematical relationships beautifully (a completely straight line on a logarithmic scale for example).
Scientific charts are for pondering at your desktop, a different setting from a 20 minute all or nothing investment pitch. When you show a boring growth line and have to alert the audience that the tiny labels on your y axis are in fact on a logarithmic scale, you have lost some of your fire power. It looks less spectacular, and more importantly, it requires additional thought steps in the brains of your audience. The hockey stick simply works better.
If you are dealing with serious science, consider 2 charts right after each other, the first (populist) one showing the raw growth, then followed by a logarithmic one that takes the responsible scientific approach.
