Yes, in this case it was a good change.

On the other hand, some of the mods' title changes significantly reduce the information content, as for example the title that was changed for that other thread today: https://news.ycombinator.com/item?id=12690853

Originally that title was something like "Microsoft SQL Server 2016 in Docker", which gave some helpful context. But they replaced that with: "Microsoft SQL Server 2016 Express", a change that was not helpful at all, since it sounds like a product announcement of SQL Server 2016 now.
