I thought by now companies should've learned to have the legal departments or external lawyers consult the marketing/PR folks (or use their own good judgement) before sending out such stuff. Plenty of cases here in Germany as well that created quite some backlash. I still remember e.g. the case of "Held Der Steine", a fantastic guy who's the most popular Lego Youtuber in Germany, where Lego thought it would be a great idea to send him a "Cease and Desist" letter because part of his logo vaguely resembled a Lego brick. He wasn't amused and with his enormous reach (millions of people watch his videos) he made sure a lot of people learned about this greedy behavior of the Lego company.
