You're missing out on the whole retroactive piece! When you install Freshpaint, Freshpaint starts tracking every click, pageview, etc. This means Freshpaint is tracking nearly every event you will ever care about from day 1. At any point in the future, you can send any data Freshpaint has collected to your different tools. In the same way that programmers try to achieve 100% test coverage, Freshpaint achieves nearly 100% "event tracking coverage" out of the box. That's not true at all with Segment and it can take several months to get even most of the events you care about.
