What benefit does this have over a Zigbee dongle on Amazon that’s cheaper? Would the advantage be that this is a 3-in-1 dongle?

I want this to be real.

Depends on the community. I’ve met some very helpful noob-friendly developers who recognize you’re a noob and will use simpler terms to guide you through the process, and passive aggressive assholes that’ll ignore your messages the very second they figure out you’re a noob. Even though they were literally just talking to you seconds before.

There must never be a single dominant instance. If one instance becomes too large, they end up having too much influential power. And with all that power, big corporations or power tripping admins will use that power to coerce other instances to do certain things. “Don’t want to follow our unilaterally-imposed rule? We’re gonna cut off your entire instance and your users will lose access to our communities.”

If Meta doesn’t get defederated, they will become the dominant instance. They already have the most amount of users since I’m assuming you can use your Facebook/Instagram account, they’ll have the most amount of user activity, and of course the most amount of power.
