I’m only subscribed to about 10 small communities, where it’s stuff that I love but the communities are small enough that they don’t really reach my all feed.

From what I understand, the attackers steal your number by gaining access to your phone carrier account.
They can gain access to your account either by finding your info in a data breach, or by phishing the account details from you.
That’s why they say that you need to setup a strong password with 2FA for your phone carrier account to protect yourself from this kind of attack.
