Wishful thinking. Look at Wikipedia. Open everything, total content dumps available as single tarballs, “free the communities” as one of their founding tenets when it started, lots of spammy mirror sites, yet everyone is still stuck there. Main reason is the stupendous search rank makes everyone go there. This is one reason I decided to block search engines from my personal site. It’s ok, no one reads it either way.
As other people have explained, basically it’s a viewpoint supporting the existence of Israel. Israel itself is sometimes called “the Zionist entity” as a propaganda term by its opponents/enemies, as a way of refusing to say the name “Israel” or acknowledge it as a country. You might have heard the term used that way and picked up the undertone. It’s like saying “the orange-haired figure” as a way of pointedly refusing to say the name Trump or calling him the president.
