It is a way to increase usability for casual users, decrease spam by requiring some other source of identity tied to real existence (emails are easier to generate than throwaway phone numbers).
It may decrease privacy philosophically, but it isn't nefarious.
If you want a private messaging platform with zero prerequisite identity, use Briar.

You can keep it as an option.

Phone numbers never been a good way to counter spam, just look at social media, you can buy phone numbers in bulk these days, not to mention spam might work in social media because there’s the concept of “public space” where everyone shares and talk, so it does make sense for some bad actors to spam or even trying to influence others, that’s not the case in messaging app, because first I need to know your “unknown” username that I can’t see it elsewhere, and second, the efforts are worthy for such unsolicited message, which in case it was, you can get a burner to send it. The point is requiring a phone number to counter spam doesn’t work, and it doesn’t make sense either for messaging apps.

Well, personally I don’t use Signal, never will in its current state, but they always try to promote it as privacy messaging app while still relying on a broken system known as GSM.
A lot of spammers opt for media that does not require the effort of obtaining a phone number. It's the bike lock model: no bike lock is ever safe, but as long as your bike is parked next to bikes with a weaker lock, you have a pretty good chance of not having to walk home on foot.

It doesn't decrease privacy. It decreases anonymity which is distinctly different.

Or Session which is a fork of Signal that runs it's own network using standard PKI instead of a phone number for identities and a decentralised message delivery/onion routing system.

You either end up discriminating against users who have to use VOIP for whatever reasons (and there are legitimate reasons) by blocking VOIP numbers, or your barrier to entry for spammers is almost negligible. It's not a good system.
If you want to prove that users are humans, use a webcam and an id, or delegate the task to some bigcorp who already has a similar system. If that's too much for you in terms of privacy, you shouldn't be attempting to prove that users are humans in the first place. Maybe you should prevent spam via product driven solutions, e.g. whitelisted contacts.
For the people who really don't want a phone number, make them pay via mobilecoin. Lets them raise money and prevent spam.
