There is a pretty substantial difference between losing one bundle and losing the whole of classic though.

TBH I doubt that Humble will be able to offer so many games that I want every single month, so I wonder how often it will make sense to upgrade a Basic Monthly to Premium. Depending on the line-up, 3 games could be already a rather excellent deal.
In a long-term view, you (generic you) IMO shouldn’t fixate too much on quantity (although some yous will definitely have reasons or preferences for more games) but what quality, and wanted, games can be squeezed in Basic.
Perhaps an email snafu or simply a delay?
I’m unsubscribed, too, and they sent that email. It makes sense to raise awareness of the switch as much as possible.
No reason to leave out a former customer I can think of, other than bad standing.
