The screenshot answers your first question, but I went into more detail about it in this post nostr:note1hrs6947q7rf0ysp638f6pw5d9g5enzl32qr5uj4at2p5upt0qufqrhdnru
No better alternative "exists" because the better alternative would be nostr without the bridges, and the bridges deny the possibility of that existing
Some of the complaints make no sense. How would non Nostr users find your posts without the bridge? They’d need to be on Nostr or a Nostr user would need to share your posts on another protocol/platform. Gleason isn’t the only one with a bridge there’s another bridge, momostr.pink
There shouldn’t be a singular protocol ruling the Open Social Web. There should be a very open way that all connects ATProto, ActivityPub, Nostr, ATOM/JSON/RSS etc
I do believe anyone making bridges and running relays should do a better job managing spam, I don’t give af about “censorship” of spam
I don't get what you mean about non nostr users finding a post without the bridge, you might need to re-read.
And if you don't give af about censorship then I don't see why you're wasting my time. I am tired of being censored by manipulative psychos.
You need to reread, I said I don’t give af about censorship of spam. Spam is a waste of everyone’s time, your post spoke a lot about spam.
You also mentioned non Nostr users, I added a screenshot. Maybe I am misunderstanding but how would those non-Nostr users find your posts without the conditions I mentioned previously ? 
"if they were here"
