These emails have been bizarre. Seemingly because I once crowdfunded the librem 5 my email address ended up on an "investor-relations" mailing list which periodically solicited, well, investments. Bonus points to the enlightened soul who realised that reply-all was open and described it as a Ponzi scheme, and to Purism themselves for having a non-functional unsubscribe page for the list. (They did remove me when I asked last September.)
