I don't know where the rumor started, but I can understand why it is plausible:

(A) The OpenVPN developers discourage the use of TAP connections,
saying, for example "Layer 3 is for a number of reasons the better
choice anyways" [1];
(B) The "OpenVPN Connect" Android and iOS apps do not support TAP
connections [1][2]; and
(C) Apple has deprecated loading the system extension that Tunnelblick
uses to create a TAP device and, on the latest version of macOS, pops
up a warning saying the extension "will be incompatible with future
versions of macOS" [3].

Best regards,

Jon Bullard
