There’s a large org (@ hope.net) that has a non-profit convention every few years. It maintains a e-mail list to let its > 1000 previous attendees know about the upcoming convention and related info. In the past decades everything was fine.
This year (con in July) Gmail has been spam-binning ALL of those reminder e-mails aimed at attendees who use Gmail. Quite clearly it’s not the users making that choice. The org is left with no other way to contact those attendees.
AND they might have had miniature cameras in them for the past 20 years.
(The laws against this stuff are almost non-existing. Option left for those of us creeped out by constant surveillance: don’t leave home, unplug that webcam. Demand privacy or lose it.)
