Sumana Harihareswara (previously) writes, "The Abstractions tech conference (Aug 21-23, in Pittsburgh) doesn't tell attendees this before they buy a ticket, but attendance requires you wear their wristband with an embedded tracking chip -- and that you don't take it off at night or in the shower till the conference ends. Organizers haven't addressed privacy, health, physical safety, and inclusivity concerns that registered attendees raised privately earlier this month, so Jason Owen is blogging about the issue in hopes of getting them to modify their policy."
