What Sentry objects to is people setting up "super-error-reporting.com" with an unmodified copy of the Sentry software without contributing anything back, which undercuts their SaaS business model. This is not a "user" in any common-sense definition of the term. And yes, these people are "getting a free ride" (i.e. "free riding") because they get software with zero cost to them. That's on its own is not really a bad thing – I "free ride" loads of stuff, as do we all – but the "undercuts our business model" is. I'm not a huge fan of the "free rider" phrasing because it doesn't emphasize the core problem, but it certainly means something different from what you're taking it means. Simple saying "your business model sucks then", as the previous poster did, is too easy. SaaS is the obvious business model for something like Sentry, and this benefits not just Sentry but also the users who don't want to self-host (i.e. most users). There are other ways, but they're much harder. PostgreSQL and Linux are mostly developed by organisations which use or offer PostreSQL and Linux as a service, so it's more or less the same business model but with extra steps. Ideally having the SaaS company separated from the software development like that is better, but also really really hard to do because it's a catch-22: you need to develop a community for the software, but to develop the software you need a community. PostgreSQL's and Linux's pre-cloud roots are a huge boon here.
