Is the idea here that you wanted the interviewer to beg you to stay on the call?

I interview for a BigCo. Most of us do it not because we love interviewing but because 1) It's a way to check the "citizenship" box on performance reviews. 2) A director or VP sent a mass email exhorting us to join the interviewer pool. Everyone I know in fact views interviewing as a chore that takes away from one's day job. But, there's standardized training and emphasis on objective tests and rubrics to minimize bias. Given this assembly line process and the fact that most interviewers want to be elsewhere, there's very little reason to expect a random interviewer to want to sell you on continuing a process that you consider yourself above.

If a candidate proclaimed that they didn't agree to the terms of one of my interviews midway through, I'd certainly exchange a few words with them to try to make them more comfortable, but in the end I would by fine with bidding them farewell and being glad that writing up that interview feedback would be easy.

Some were doing it because they had to (last-second substitute) and it showed as they were rude about it or highly disorganized.

You don’t have to take it and it’s okay to cut interviews short as the interviewer (I’ve done it before), but it’s a mistake to be unprofessional about how it’s cut short.

Those same skills that let you plug Machine Learning Library A into Tracking Database B could make things that vastly increase productivity for a bunch of regular people, and if you're doing it for yourself or a small enough shop, it could actually pay off.
