67% of Android VPN apps claim to provide traditional VPN services (labeled here as “VPN clients”) including enhanced security and privacy, anti-surveillance or tunnels to access geo-filtered or censored content. Note that we consider Tor clients (e.g., Orbot, Globus VPN] and TorGuard VPN client) as a separate category.
That seems a pretty fair distinction.
Notably, the report doesn't include the word "onion" in it at all, so I'm not sure where you got "[they] think it's related to the onion router" from.

TorGuard == something completely unrelated to Tor. Per the TorGuard website (https://torguard.net/faq.php):
"Is TorGuard related in any way to the “tor” project? No, The reference to "tor" in TorGuard relates to "torrents" and guarding one’s privacy when using bitorrent. We are not related in any way to the “tor” project however the company does support through donations."
Orbot, OTOH, is part of the Tor Project (https://www.torproject.org/docs/android.html.en) and Globus (https://play.google.com/store/apps/details?id=com.globus.vpn...) claims to support Tor.
Ok, I entirely agree they (and I) are wrong. But obviously I'm going to take the position that it isn't unreasonable to think something called "TorGuard" has something to do with Tor.
