Seems like you just haven’t been paying attention. Even commercial VPNs like PIA and others now use Wireguard instead of traditional VPN stacks. Tailscale and other companies in that space are starting to replace VPN stacks with Wireguard solutions.
The reasons are abundant, the main ones being performance is drastically better, security is easier to guarantee because the stack itself is smaller and simpler, and it’s significantly more configurable and easier to obtain the behavior you want.
I use and advocate for wireguard but I don't see it's adoption in bigger orgs, at least the ones I've worked in. Appreciate this situation will change over time, but it'll be a long tail.
It’ll take a little bit of time. But for example Cloudflare’s Warp VPN also uses Wireguard under the hood.
So while corp environments may take a long time to switch for various reasons, it will happen eventually. But for stuff like this corp IT tends to be a lagging adopter, 10-20 years behind the curve.
Warp actually uses MASQUE (UDP/IP over QUIC) by default

Bigger orgs for the most part use whatever vpn solutions their (potentially decade old) hardware firewalls support. Until you can manage and endpoint a Wireguard tunnel on Cisco, Juniper, Fortigate (etc) hardware then it's going to take a while to become more mainstream.
Which is a shame, because I have a number of problematic links (low bandwidth, high latency) that wireguard would be absolutely fantastic for, but neither end supports it and there's no chance they'll let me start terminating a tonne of VPNs in software on a random *nix box.
If you use Kubernetes and Calico you can use Wireguard to transparently encrypt in-cluster traffic[1] (or across clusters if you have cluster mesh configured). I wonder if we'll see more "automatic SDN over Wireguard" stuff like this as time goes on and the technology gets more proven.
Problem is IIRC if you need FIPS compliance you can't use Wireguard, since it doesn't support the mandated FIPS ciphers or what-have-you.

sure, but I mean "road warrior" client. Typical, average company VPN users. Ironocally getting a technology like wireguard in k8s is easier than replacing an established vendor/product that serves normal users.
The anti-FIPS position of the wireguard implementors is a big problem for adoption.
Exactly. We've looked at using Wireguard at my company, but because it can't be made FIPS compliant, it makes it a hard sell. There is a FIPS Wireguard implementation by WolfSSL, interestingly enough.
Yeah itll be running out of steam not only when regulators _understand_ wireguard, but when its the recommendation and orgs need to justify their old vpn solution
OpenVPN makes SNAT relatively trivial, from what I can tell. So I can VPN into a network, use a node on the network as my exit node, and access other devices on that network, with source-based NAT set up on the exit node to make it appear as if my traffic is coming from the exit node.
Wireguard seems to make this much more difficult from what I can tell, though I don't know enough about networking to know if that's fundamental to wireguard or just a result on less mature tooling.
WG is no different really, but you'll have to set it up yourself unless you use a client like tailscale. WG is just bare bones and you're supposed to use a proper client.
Add SNAT rule, enable forwarding, add allowedIPs to WG config.
Right, so my understanding is essentially correct. OpenVPN makes it trivial to set up a VPN which lets you access a remote LAN, without having to involve third-party SaaS products like Tailscale.
