Is Atlas VPN not free anymore?

Hello there, I've been using Atlas VPN for a while now and I've noticed something interesting. It seems like they've changed their policy or something because I can't seem to access their services without paying. I remember when I first signed up, it was advertised as a free VPN service. So, I'm wondering, has Atlas VPN stopped offering their services for free? Or am I missing something here? It would be great if you could clarify this for me. Thank you!
