Yes, the idea that this company paid a lawyer to go through its tech stack and figure out who owns the code relied upon by the company is fairly ridiculous. Either a lawyer drafted a template email for the company to send to its suppliers, or a lawyer (read: intern) was given a list of suppliers to email on behalf of the company, or a lawyer wasn't involved at all.

But in software communities (and particularly in FOSS communities) tech people can do no wrong; every time a tech company does an aggressive or foolish or otherwise objectionable thing, there must be a dastardly lawyer somewhere pulling the strings.
