Long-term blue teamer here. I don’t entirely disagree with you but there’s a little bit of minor nuance. In a general sense, many do use them interchangeably.

RCE is remote code execution. Some amount of code can be executed remotely.

ACE is arbitrary code execution. Unrestrained code can be executed.

That’s why many critical CVEs often have the verbiage “arbitrary remote code execution” to denote not only can code be executed remotely, but practically any valid code can be executed remotely.

I must be too old but I do not get this one iota.

Not trying to be offensive but I seriously doubt there are “as many art styles” in the furry scene vs the entirety of art that isn’t furry…
