You may be right. You can not even usually go back to an older version of an application if you want undo some bad decision by the developer. Source code is spotty if you can get at it. Your data is locked in by them on some server you do not control. In some cases they do not even really control it. I would add the other anti pattern companies use is opensource vendor lock in. They take what would basically be a 'meh' product and put good stuff ontop of it. But to get that 'good stuff' you have to buy their service contract. Sure you are using some open source. But the key bits are still proprietary.
