>They want you dependent on them and locked into their ecosystem.

This is a strange conclusion to come to when clearly a lot of effort was put into developing an open standard (Credential Exchange Format) to make it easy and secure to move credentials between vendors/ecosystems, without opening end-users up to phishing attacks on credential export.

If big tech wanted to lock people in, it seems like it would have been a lot easier to just... not create an open standard.
