People are being really hypocritical.
You want a free open source social network. But when people you dont like join it, you hate it. That is not how it works, its not how FREE in FOSS works.
Meta can join, they can do whatever they want. It literally the point of this social network. If you dont like it, then go to a social network that is not FOSS, but is heavily moderated, because that is what most of you really want.
Croatia here,
tap water is completely drinkable and safe without any boiling. Exception are some more remote islands, so if you are going on some island, chekc if the tap water is drinkable.
Fun fact: Croatia actually uses drinkable water for toilets as well, altough i would not drink from a toilet :)
