I remember a time when visiting a website that opens a javacript dialog box asking for your name so the message “hi <name entered>” could be displayed was baulked at.
Why does signal want a phone number to register? Is there a better alternative?

But the police request the meta data of all messages from your phone number that the company has and they’re required by law to give them it.
These are all the court orders Signal has complied to and details all the information they give up

TLDR; they only give the last time the account connected to Signal servers and the time of account registration or re-registration
You should go properly read the requests from law enforcement they have received and exactly what information it contains. It’s public. Then evaluate if it matters for yur threat model. Security doesn’t exist in a vaccum.
Its encrypted
Messages are e2e encrypted. Metadata is not encrypted.
Edit: I feel the need to qualify this statement. Metadata about your connection may be encrypted at rest but is decryptable given that signal is released metadata to authorities with a warrant/subpoena.
Yes it is. Signal isnt PGP email. A lot of work went into protecting metadata.
what? can you show a source? I think you mixed it up with Matrix
They can “request” it all day long. Signal doesn’t store them beyond the time needed to deliver to the end user device, and while (temporarily) stored, it’s encrypted in a way Signal’s service cannot read.
huh? so the phone number is encrypted in a way that can’t be read, but an sms is sent to the phone? … a separate company sends the text on behalf of signal? so that separate company logs the phone number, the timestamp and who knows what else.
Signal doesn’t use SMS anymore, and all messages are sent over encrypted Internet protocol. Any servers in between won’t see the phone number, it’s not needed to deliver the message, it’s using an IP address at that point and the entire message metadata is encrypted. Signal is the only one that can see the phone numbers, which they use to identify multiple clients as a single user and route messages accordingly.
Signal doesn’t use SMS at all, once you have enrolled. The phone number is used to validate people and exclude bots, during registration. As others have noted, you can hide your number from other users, as well.
Secret sender stops any real amount of information about messages being connected to you
