Not all abbreviations are acronyms, only the ones that take the first letter from each word. Lego takes two letters from each word, so it’s not an acronym.
On a similar note, some but not all acronyms are initialisms, if they’re spoken as the letters rather than the “word” they create.
FYI, DIY, PS are all initialisms, and also acronyms, and also abbreviations. ASAP, SCUBA, and LASER are acronyms and abbreviations, but not initialisms. Lego, appt, and st are all abbreviations but neither acronyms nor initialisms.
I think the “correct” usage of acronym is only when it is spoken as a word. But language evolves and all that.
You can see the tension in the way MW defines it (including the extended description). Like: here’s the definition of the word, but some people use it when they actually mean initialism. This is in contrast to your more concise and cohesive definition of “[abbreviations] that take the first letter from each word”.

why is english like this… we just call it “shortening”.
Why does a language have different words for different concepts?
