How is it mean to say that @Alby is a centralized service?

Where does the @Alby software run from? A centralized server

Also, how is @Alby existing, more important than educating people to stay away from centralized data honey pots like @Alby ?

Anything centralized and having controlled access (invite links, email capture etc) is against the principle of #bitcoin being open to anyone, anywhere, anytime, with no questions asked 

 We build on open protocols. You could always use Alby Extension without Alby Account (so email, etc) and with us not knowing anything about you. The same will be soon possible with Alby Hub.

We literally just release open source, self-custodial wallet. You can fork it today and get rid of Alby Accounts if you want, instead of complaining
