I had hoped and frankly expected that there'd be a few more privacy oriented choices in this space by now. There was Zoe[1], but that got canned at last minute. I really didn't want a refund...

In short 5 months ago all seemed to be going OK, then they went a tad quiet. Three months ago there was another update including a CEO statement.
"Due to unforeseen delays in the development, we are not going to deliver the ZOE in the current form and all contributors will be refunded." They mention it's a partner having development delays in some critical component, but all very vague with no details.
Supposedly the project is alive and we'll get an update email when they're ready to try again. I infer from refunds all round it's not going to be soon. If it was just a few months I figure they'd ask for patience to work around whatever issue.
I don't know enough of IoT specs, protocols etc to know what would be needed other than the broadest terms. Probably yet another use for a Pi 3.
That is the most important distinction. Sure my laptop has a camera but if I keep good security practices I can feel reasonably assured that it is not monitoring me unless I've switched it on for some reason. The Alexas and Google Homes of the world default to "on", and everything you do/say is monitored because "cloud processing".
I will always have a problem with anything that tries to use my actions to build a more predictable model of who I am or what I am/will be doing
