Yes, I do understand this is a users forum. Hence my "futile rant post" acknowledgment. I also understand uninstalling previous versions as standard practice. However, Legacy has a different use case (IMO, or perhaps just my usage and those who actively used Legacy) due to the evolution of the software. Part of what I find unacceptable is that EN silently changed the behavior of the updater by adding an action that eliminates access to a user interface.
I hear your point. It seems to only apply to completely new installations (i.e. Legacy without current version), since Legacy / current version dual users would have already had that drive space allocated. I use both, and so Legacy data was not orphaned or obscured, but actively used — as was the space for the current version (unless I misunderstand how Legacy and current version are stored). Removing Legacy without notification only removed the interface that allowed me to access my data.
