The developers' response: "As a way to ensure that the installation is a clean one the installer removes the contents of the install directory before writing the new ones."
I am beginning to not take them very seriously.
This is very misleading! What was actually posted was Travis saying:
I saw the dev response to Dave's urgent email, so I'll relay the message. From the devs:
As a way to ensure that the installation is a clean one the installer removes the contents of the install directory before writing the new ones.
So, since you tried to put the file directly in the 'games' folder, it was working on cleaning everything out. I'm glad you caught it before any real damage was done. The team has disabled this clean-out "feature" in Unity. We'll have to see how that affects future updates. If only we had an automatic updater, right...?
By taking that one line out of context, you dodge the annoying reality of Travis acknowledging that this was an urgent problem, and a problem they're fixing.
Travis also quoted a line out of context. You don't know what the rest of what these "devs" had to say was. They were, after all, not talking to customers.
I mean really guys. Focus your anger on real things, not imagined detachment. We already knew they were deleting the files, and that quote doesn't say anything new or interesting.
