Same boat here. I've turned so many friends on to software defined overlay networks over the years and most can't understand how ZeroTier is free for everything you get. I use both Tailscale and ZeroTier for different purposes. With ZeroTier L2 bridging comes at less of a cost than with ZeroTier. I honestly wish Tailscale has a bit more flexibility and functionality in their routing capabilities. Both are fantastic though and I highly recommend both! I'm also surprised that ZeroTier hasn't been acquired. I was working for a prominent network security vendor about 6 years ago and mentioned to some higher level product folks that ZeroTier is basically "next-gen VPN" and how it would be a fantastic addition to our product suite. I remember getting snide comments about we already did what ZeroTier was solving for. However DM-VPN type implementations aren't remotely like how ZeroTier solved for and now I think the light bulb has likely lit up for those folks given how all the Zero Trust / Perimeterless / SASE / SD-WAN have taken off. Totally agree that most of the "enterprise" solutions are just garbage built on OpenVPN or overly rigid IPsec implementations with poor performance and even worse functionality.
