In lots of cases you are dealing with people that when you say "MPLS" they understand "site-to-site L3VPN using some magic technology" (that they don't understand). Others do understand some tiny bits but see it as a "carrier technology". And there's enough of them so that manufacturers take their opinion in consideration. Result => VXLAN.

When exchange points started using it (VPLS) to operate the member
fabric, you know it was downhill from there :-).

And that was way before all this Cloud/DCI/VXLAN/SDN/SD-WAN monstrosity
our industry finds itself in :-).
