While I have a facebook account I'm not a big user, it's mostly for a few contacts that are only on messenger. I don't look at my "stream" a lot, and when I do it's mostly useless content like meme, self-centered post and whatnot that I personnaly have zero interest in, with maybe 1% of actually interesting thing in between like birth annoncement from acquaintances etc ...
I don't plan to delete my account because I want to keep the ability to be in touch with those few friends, and I haven't reached the point where I want to delete the messenger app, but the main FB/messenger duo just doesn't fill any major need for me.
But two things that struck me recently:
1. When opening my stream just to gloss over, there is A TON of ads. Like, the first 4/5 posts are real, then it's one post one ad one post one ad. And the targeting is abysmal. The only ones that are kind of on target are the amazon retargeting, except in typical amazon retargeting fashion it advertises to me stuff that I have already bought (on amazon no less). At least google has the decency to show me stuff I may be interested in, if vaguely.
2. I'm not sure when this was added to android, or if this is a specific samsung thing, but I had a weird warning that I had never seen before: my phone warned me that messenger, while not being open, was trying to access the "microphone" permission. Kudos to android for blocking it and warning me, so I could disable that permission for good. I can't think of a single reason for that app to do it that isn't super evil.
I'm also 99,9% certain it's not even legal where I live (France), I can't record my customers without asking or warning them on each instance of a conversation and with a clear non hidden message, so I doubt they can do that no matter what's in their TOS.
