Added to my list of troubles & worries I avoided because I didn't rely on a random external company for critical infrastructure.
However, never rely on an external provider if there's not a low-risk offramp plan. Can I export all of my data and easily migrate, worst case scenario? Are there open source options using the same or similar formats/workflows/etc? Is the format itself proprietary or lock me in otherwise? Those sorts of questions need to be figured out fully before jumping aboard.
