I upgraded from Quicken Classic for Mac because their publicity promised investment analysis features such a calculating IRR and ROI on investments. But it does nothing of the sort, it only list cost and current market value of investments. That information is trivial and easily available on the original Classic for Mac.
When I saw this, I tried to cancel the subscription, but was told that that only after the renewal year was up could I downgrade back to the original Classic. And nowhere can I find a phone number or an email to complain. I am old enough to remember back when (1980's) Quicken reports in Mac could all this and more.
Cory Doctorow has written a book about this kind of behavior by large digital companies: Enshittification: Why Everything Suddenly Got Worse and What To Do About It
