My understanding from Etresoft and others (I've not used a VPN) is Apple provides the hook to connect to and seamlessly uses a VPN but does not provide a VPN service. Are you saying they are incorrect? You are merely turning it on and using Apple's VPN?
Y’all are seemingly confusing the integrated VPN client with a commercial provider of network monitoring and data-collection services.
Some commercial VPN providers may well use the integrated Apple VPN client and probably with a profile for same, while other commercial VPN providers can install a VPN client app. Streisand and Algo work similarly, though these VPN servers are operated by and entirely under the control of the user.
In any of these cases, the VPN client necessarily connects to a usually-remote target VPN server.
The target VPN server can be at the perimeter of or can be within the target network of an affiliated organization, or can be a VPN server that the user is hosting and running within the such as Streisand or Algo, or can be a VPN server operated by a commercial provider that claims to protect traffic against an ISP or coffee shop eavesdropping. The former VPN configuration provides end-to-end encryption to or into the target network, while the latter two cases provide encryption from the VPN client part way to the user’s intended target network destination.
Again… Apple absolutely provides a VPN client with iOS, iPadOS, and macOS, and it works. Apple previously provided a VPN server with macOS Server (up until 5.7.1, IIRC), but that all got retired a while back. Nowadays I’d recommend using a firewall-embedded VPN server for many SMBs seeking end-to-end or end-to-perimeter VPN encryption, though there are other options here.
For those folks reading this looking for first-few-network-hops security, use HTTPS and SSL/TLS for all your connections, or use Streisand or Algo and your own VPN server. I generally wouldn’t prefer to use a commercial VPN provider, though there can be some cases where that might be appropriate.
To the OP: restart your iPhone and try again. Then check for installed profiles. If this iPhone is managed by an associated IT group, check with them.
