Oracle sponsors our university to teach their flavour of SQL (Oracle SQL, not MySQL) with their management software rather than any of the competitors, free or otherwise. One of the DBA teachers once told me that there are enough differences between Oracle and other flavours that the knowledge isn’t immediately transferrable, so when students graduate, all they know is Oracle, and they perpetuate the cycle.
This is obviously an unfair anti-competitive practice, but crimes are only illegal if someone enforces the law.
Microsoft has similar practices, and I would be very surprised if other business software companies like IBM or SAP don’t do the same wherever possible.
