With FEP-c118 there is currently an extension to the activitypub protocol in the works to allow setting a license on posts. If you don’t add a license info in your posts the licensing is unclear. I think that some jurisdictions give a default copyright and some protections to the author but I don’t know how that works.
With the fediverse you you have as much or as little rights as when you put it on your private blog without explicit licensing. If someone uses your works without your consent you still have to find out and you have to protected your rights yourself.
There are currently no lemmy or kbin instances that have monetization options. The only ActivityPub software I know that can show ads is misskey.
In the end you have to be aware that any kind of open social network is like screaming your thoughts towards a big crowd. You lose most of your control over it the second it’s out. It is nearly impossible to track who has the information and who shares it with others.
There are legal protections in some parts of the world but even then you first have to find out that something bad happened. If an instance were to start monetizing data it would probably cut off pretty fast and all the communities would probably move.
Still if there is stuff you don’t want everyone to know don’t post it publicly.
HA might be possible in a active passive configuration if you don’t have any dependencies on external hardware like a zigbee stick. Active active would need support by HA and I don’t think that is implemented.
I think the most secure thing is to keep regular backups so you can roll back easily.
The problem is that it will take ages for them to get any adoption in a new browser. Firefox used to be a big player and then chrome came along. Now most of the people don’t even try Firefox anymore. I still hear a lot of “Firefox is slow” sentiment even though it isn’t.
The problem isn’t Edge in itself. It is good if there are many browsers. But when Javascript became more than just a play thing, all of a sudden browser slowly moved to chromium as an engine. There used to be Opera, IE, Edge, Firefox, Safari and Chrome with each their own browser engine. Now there is only Chromium/Blink, Safari and Firefox left. Google is way too powerful with their marketshare. They constantly try to implement features that are bad for users.
The great thing is that if a lot of people like Mastodon they can use it and if you don’t like it you can use something differenent and you will still be able to communicate. That’s the whole point.
