@kaniini if you’re talking about elasticsearch, it’s like saying “well they both used $someDatabase to store data on their servers...”
Mastodon offers the promise of federation, not freedom from whatever arbitrary technology was used for evil elsewhere.
It’s true in this case, as it has been since time and memorial, that technology isn’t the scary thing, it’s how people use it.
@kaniini crawling an instance’s toots _without_ buying it is a weekend project for one person. When you own the db, pumping into elasticsearch takes maybe an afternoon.
If an afternoon’s work feels like a sufficient deterrent from hostile actors buying your instance and stealing your data, I envy you your lazy attackers.
Sorry I wasn’t able to put this as simply as you have...
