I mean, blob (and object storage in general) has been used as a term for a long time. It isn’t particularly new, and MS didn’t invent it.
That’s sort of the problem. It’s easy to Google S3 since it’s a distinct (if obnoxiously short) term. Blob is already an overloaded term.
An example of a great name from Microsoft is Excel, it’s relatively short but meaningless so if you Google “Excel Sum” you’ll get wonderful results… “Blob Get” is going to get you a lot of random stuff.
Edit: the top result for blob get is accurate on Google but you’ll also quickly see this result from that site we all hate:
Need help! How do I get the blob fish, basking shark and dwarf whale?
And renames a random product every month, following a restructuring it’s licensing
