Why is rocket.chat recommended?

I deployed rocket chat fairly quickly. The whole thing is a massive commercialized product. Every integration seems to require some upgrade. This includes basic things like voice calls and video. Am I missing something? I was really bummed out because the UI was decent enough, but every click is like “upgrade to enterprise”. Is there not free jitsi integration or anything?

More of a question and not a rant, aside from requirements around connecting into their commercial cloud bullshit to even enable plugins at all.
