yes microsoft was the one I was complaining about but you can't redirect phone calls in the same way as sms and sms itself is mostly vulnerable due to legacy things that they could stop using and finally that article was not just 2 factor but bringing in using sms for a password reset which is really insecure but unrelated to 2factor. 2factor will always be safer than non 2 factor because more has to be done than just the one side.
