Oracle is a shady company. They do this cute little trick where they give out free software, but if it ever appears in a corporate environment and phones home, that’s no longer free and they shake down the company the person they tricked works at. So Sharon in department X brings her laptop from home and hops on the company wifi and virtualbox phones home, now her employer is being sued. They do lot of other shit too but a general rule in the IT world is to stay the fuck away from oracle whenever possible.
