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].
Expanding further on those points, there was a discussion of this topic
here on this list back in March 2019, under the Subject "Removal of the
TAP Bridge, Strange ARP issue and looking for solutions for an
alternative Layer2 VPN", e.g.
https://sourceforge.net/p/openvpn/mailman/message/36606924/
or
https://www.mail-archive.com/openvpn-users@lists.sourceforge.net/msg04759.html
.
That disussion makes clear that in fact OpenVPN _3_ specifically does
*not* include support for TAP (at least as currently implemented).
The discussion does go on to explain that that all releases of OpenVPN
_2.x_ will continue include TAP support and that v2 "will live for a
long time to come"... but I can certainly understand "casual" users
being confused by this distinction.
The OP in that thread did not give an explicit reference to the origin
of his/her information regarding TAP support/"bridged networking",
so I'm not sure what would have helped avoid the confusion there...
... but I searched around a bit in the Community Wiki and though there
are a number of pages that mention specific OpenVPN 3 software
packages,
I didn't find any general page explaining the differences-between and
future-plans-for the v2 and v3 (and "Connect") product lines, etc. --
something like that might help clear up (a little of) this sort of
confusion.

I'm sorry I didn't recall what I wrote couple of months ago but it's
amusing that some people even takes the time to read up on old dirt and
if we talk about dirt this NetGate article is the shining example what
would qualify for some bath room writing hodge-podge where the author
didn't give half a shit even to use a <code> [code] statement (most
likely even that config he posted is broken).
That kind of shitty forum posts described the linux community well for
the last 20 years. Someone might knows the right answer or might find it
later so he leaves a half finished rant which does not work and most of
the readers don't even understand and let them find it out on their own
and when they do they will of course NOT share the right answer with
anyone LOL.
I guess in 2020 we should be done with that type of crap quality. Just
write a proper step by step howto please on OSPF+OpenVPN but what would
be even better to have an "ospf" one liner option and when you put that
into the OpenVPN config it will just do the magic trick.
Thank you :)
