Manipulating DNS is sadly very easy, but a TXT record of this type should be better than a MX record, as long as a oauth signin also contains a normal login link.

In this case, the worst-case is an attacker injecting a TXT record to force OAuth logins via that domain... which is a bit pointless as far as I can see, it either won't work or use the victim's own oauth service, for which they are responsible themselves IMO.
