My understanding is that it wasn’t so much that the content was problematic (the beholder stuff was hard to see that way) but that they decided to change what was world specific versus whole game. This was also one of the reasons to stop selling Volos and Mordenkainens tome of foes completely which not only has some awesome lore but that lore made it into Baldurs Gate 3.How much errata should change is open to debate - but some people found parts of the original version of the books offensive. If I really cared that they might change something I'd buy the book. I never looked at the Eberron book since while I find the setting interesting I run a homebrew campaign so I didn't need it. But yeah, it would have been better to give you a heads up.
You can see what they changed if you look up the errata. They did remove a whole 2 paragraphs from Volo's on half-orcs. I don't see anything to get particularly upset about. If I happened to buy a printing of the book after the errata you would also be missing the original text. Should they have left the text and imagery for the Hadozee in the book as well?
Regardless, you don’t get to decide what you want to keep or toss aside. They do. For any reason they want. It’s right there in the Terms of Service.
