you're probably right. i think everyone would have been fine with "crazy uncle brian going off on a tangent," and leaving me be, except i didn't tangent.
when i left facebook i just left and when i left whatsapp i told people about signal two weeks ahead and then just left with that one message.
i think the problem was that i had convinced the patriarch of the group to join me and people wanted to be in contact with him, so the dissatisfaction was directed toward me.
ironically, i was the one who talked down the group from the fearfully dire outlook about social media when we discussed the netflix "documentary" "the social dilemma" a few months back.
i thought the latter part of the documentary that had the predictions of our society being destroyed because of the revelations exposed about what social media is doing to us was cringe and i explained to the group why.
OTOH, i told people "yeah, the first part is totally true and not a revelation. they are absolutely hacking your social biology to get you more engaged in what they have to offer. it's not a surprise to anyone really as the ML systems and technology that optimize for that are well understood and pretty standard. heck, i've even written some of those algorithms myself."
that's actually part of why i left facebook. i realized that i had become complacent about things i should not have become complacent about.
fwiw, my productivity and happiness have increased dramatically since i left facebook/whatsapp. YMMV
