As a more serious and well-known concrete threat, this type of data is regularly aggregated by data brokers, and then used by stalkers and domestic abusers to commit crimes.
I imagine it being available and cheaply for sale is also a boon for various financial crimes/fraud.
It's not home depot specifically to be worried about knowing a little about you, but about them not being competent to control that data and everyone's little bit becoming a lot more significant and dangerous when combined.
edit: Also, the same type of information can easily be used later by government. I imagine if Uyghurs were not being specifically targeted by the Chinese government for cultural extermination there would be little trouble in their cultural identity being discernible from certain purchasing profiles. Once they are rounded up into camps, the last 15 years of detailed surveillance about them becomes very troublesome for them.
Never heard of them selling to individuals but it wouldn't surprise me if they do. At the very least a record should be kept of who they sold the data to in case it is used for a purpose like stalking someone.
