I think people tend to memorize how they use software so randomizing / frequently changing your UI is superbly bad, in that I agreeing with your point and that part of the article.
The trouble I still see is that most software is barely held together built on top of stuff that is even worse. From my experience, if it is running on Android or Windows, it is 100% guaranteed you will have an issue you didn't predict because some set of users have done something crazy to their device. I guess you could always leave these things broken for a while, but it would reflect poorly and is hard to convince others that "oh this crash is ok".
I guess tl;dr I think most software is broken and always broken and updating more or less frequently wouldn't really change the brokenness for users, but the frequent updates at least give them hope fixes are coming and their feedback matters. Knowing you'll have this bug forever makes any alternative attractive.
