> C has enough actual fans that I bet it never really goes away, but it won’t be useable in professional contexts after a while other than for maintenance, because people outside tech will start to call bullshit on the EULA liability shield.

That's an extraordinary claim indeed; if people outside tech were going to call bullshit on EULAs as a liability shield, they would've done so in the last 50 years of software sales.

Reliability or the lack thereof has never been an impediment to some piece of software getting popular, but to me, you appear to believe that people want more reliability from software than they have been getting thus far.

Your belief is at odds with reality.
