The problem they're solving is that a lot of people just enter their email wrong and then wonder why they didn't get the signup email.

> Like if someone tries to register an already registered email, send an email about it don't leak that it's registered.

This is something that's cargo-culted far too often. Maybe for some services it's worth keeping secret which emails are signed up, but for most it isn't.

I'd prefer to just have it. Seems decently important for me privacy wise. I as a customer don't want others to be able to test whether I have signed up somewhere and also it is much better security wise and not leaking business data.

And most times, it is standard practice to hide sign ups, luckily.

If e.g. the service allows people to search for their friends by email address (and many do) then hiding the signup is meaningless.

for most it isn't

It depends more on an email address, than on a service type, because it’s a part of a personal information that a person owns.

And what proportion - especially what proportion of people who make mistakes when entering their email address - do you think will pay any attention to that?

Privacy is always important. And validation doesn't stop typos either.
