To me there’s a major difference depending on the cost of the provided service. I don’t know what features crowdsec provides, but if it’s mostly providing lists and all the blocking etc happens locally, I don’t see how they lose much money on this free service. Gathering the lists is something they’d have to do anyway to service their paying customers.

If Cloudflare stopped making Cloudflare Tunnels free to use, I’d be more understanding since bandwidth costs them relevant amounts of money.

Matrix won’t necessarily download all state/messages automatically, but if your client requests a non-available message your matrix server will query other matrix servers for it (backfilling).

E.g. if you scroll up to older messages, it might take a a few seconds but your client should eventually show them.

Matrix server use a back-off for servers sending messages, so if your server is offline for many hours, it might take a day for your servers to get messages pushed to by other servers again.
