While you are technically correct, you also misunderstand who the target audience is and what language is required to actually make people understand.
When speaking to a normal person you don’t want to slap random jargon and care too much about precise definitions. So in that context spontaneous is a great word to describe what is happening. People without deep backgrounds in the field will not understand technical jargon and it will only make them not pay attention.

Spontaneous is actually the thermodynamic jargon in this case though :)
No, I’m explaining the pedantry, not agreeing with it. I said almost valid pedantry.
