I use a Facebook Container to block their tracking. Why is Facebook used on the Home Assistant forum when reading a topic??
Discourse has a plugin which includes social media sharing options, including a Facebook button.
I donāt see any facebook reference, just the āusualā google analytics
Click the 
icon below a post. Itās in the pop-up. Like this:
I donāt think this comes up in normal reading.

I see no facebook communication attempt, even with the button shown.
I guess that āfacebook containerā is a tad too paranoid 
Only when reading a topic. The Facebook Container block icon is showing in the top right corner of the page. BTW, I think @mattdm is bit right. I don have activate the āshare linkā to get the Facebook Container icon, it is always there when reading a topic.
I block Google Analytics by my uMatrix Plug-in.
Iām also paranoid, so it fits my needs 
<button title="Share on Facebook" id="ember453" class="btn-default share-facebook btn no-text btn-icon ember-view" type="button">ā
<svg class="fa d-icon d-icon-fab-facebook svg-icon svg-string" xmlns="http://www.w3.org/2000/svg"><use xlink:href="#fab-facebook"></use></svg></button>
Me too. Better safe than sorry 
Using Pi-Hole and set as wildcard into Blacklist globally:
(\.|^)facebook\.com$
(\.|^)fbcdn\.net$
and additionally, just to make sure that nasty data leech wont be able to send too much personal data to its mothership, Iāve added Anudeepās Facebook Blacklist to Group Management ā Adlists.

All fine. Just trying to dispel the FUD by saying that, afaict, the HA forum does not communicate with facebook in any way (until you press the button, ofc).
Even the icon itself is local to the HA forum.
What the āFacebook Containerā extension seems to do, here, is actively preventing you to do anything related to facebook, i.e. sharing in this instance.
That"s quite different than the dramatic title of this thread

Well, that is a kind of overkill

It doesnāt prevent it. It isolates this activity so itās not associated with the rest of your web browsing.
Well, if the share button is disabled, you mean you have to open a containerized facebook to manually share the link, right?
Fair enough, but does not warrant a popup if you do no such thing, as I understand the OP
No. Itās not an OS container, it is just a separation in the browser. It is entirely transparent.
As far as I understand the description:
What does it do?
Facebook Container works by isolating your Facebook identity into a separate container that makes it harder for Facebook to track your visits to other websites with third-party cookies.
Facebook Container is useful IF you have an account with Facebook.
None of us have such thing, not even the teenagers. Thus this extension might not be useful in our case to keep the data leech away? (by āusefulā I mean an added extra facility to keep them away)

No Whatsapp or Oculus quest?
anudeepND 's facebook.txt:
Host file containing domains related to facebook.com. This file doesnāt block other Facebook products such as WhatsApp, Instagram etc.
lightswitch05ās facebook-extended.txt:
A hosts file to block all Facebook and Facebook related services, including Messenger, Instagram, and WhatsApp.
WhatsApp is installed on some older phones here with minimum data.
No Oculus quest here. We are trying hard to avoid all Meta products.
What makes you think that Facebook would only track and sell your personal information if you happen to have a Facebook account?

Nothing. Thus I am using tools like i.e. Pi-Hole, NetGuard, Blockada etc. with the necessary block lists to avoid them as good as I can.
Should be clear already with my replies here that I am quite a FB-hater

Join the club. I donāt even use WhatsApp other Facebook derivativesā¦
The problem is, you canāt fully avoid Big Tech data grasping without having an IT master degreeā¦ even then it looks like it is impossible. I only try to minimize as far as my knowledge (and others) goes.
