It happens all the time. Some anecdata: When Garmin bought Navionics they cancelled everyone's paid lifetime licenses, pushed updates demanding logins (worse in this case than others because 99% of the places you'd use their software have shitty internet, so an intermittent login wall is a bit crippling even if it were free) and monthly subscriptions, and hounded every negative review saying that they were doing it for the users' own good. Could a person sue for $19.99 and not have corporate lawyers juggle you between headquarters in Kansas and Italy? Maybe, but it's a pain in the ass for minimal gains.
