It will always be cheaper to buy $1 if it's being sold for $0.30;
The trick as a business owner is:
* Will I be able to use this service until they rug pull?
* Will they exist for the life of my project?

Paying $50/m for complete ownership of your video platform is not only comically low it's almost absurd. I pay more than that for SaaS tools like Fellow or Bonus.ly; that's before you start talking about Asana or Figma or the myriad of other tools.
That something is cheap is not an excuse, jitsi is very easy to use and easy to host. Though I will recommend going with 8x8 simply because it helps fund development and people are terrified of actually owning anything these days (because they said they didn't like sysadmins and now ops skills are worth spending 11x more for a service to not have in your company, which is another topic entirely).
