Yeah, I parsed them as wanting a free system as in one that's open source, but I could be wrong. If we're talking about hosted solutions, I agree it's mostly silly to refuse to pay... unless we're talking about open source projects, where many CI vendors do have a free tier... Anyway, I also see an opposite bias toward costly hosted proprietary solutions and a refusal to even think about how one could accomplish one's goal with, say, a couple of shell scripts and cron jobs—or a self-hosted open source system. That bias can be very sensible, but it can also be a hindrance, especially when it turns out that the proprietary solutions aren't quite what you want anyway, but since you're opposed to writing your own scripts, or running a more flexible system on your own servers, you settle for a suboptimal setup... This bias I'm talking about is also a way of undervaluing something. It's saying "I'll pay $99/month for some hosted thing, but I'll never spend a week of engineer effort on really getting it right."
