Being a digital hoarder, myself, it's still quite tempting.
edit: For hoarders remember they have free books each day on Packt. They put an annoying captcha to stop you automating the download though...
I am a bit skeptical about this list as there isn't a single book that I recognise, but I have read at least one decent PacktPub book, so I was willing to take the risk.
You can skim through the books and at the very worst they'll just tell you what you already know. The Machine Learning with Go seems interesting as it's off the typical Python/R/C++ path.
But I always worry with a big acquisition that they might change parts of the platform I like, and so that's my biggest concern.
