> If people are concerned about the gem installation (and not the promotion itself), I can suggest that you promote harrow differently. Maybe put it as part of some command's output. Like "Cap by codebreaker (thanks to funding by Harrow.io)" or similar.

Actually we wanted to ping people once not on every time they use the tool, this is the lesser evil, it also allows us to push something to turn off the integration without having to bump Capistrano's version for no reason, simply by deploying another (noop) version of the integration gem.
