Whether they are actively trying to lock you in, I don't know. But neither are they making great efforts at interoperability. I've had personal files becomes inaccessible before because they were in proprietary formats and the program no longer ran on my OS. That "lock-in" may or may not have been intentional by the software maker, but the effect on me was the same regardless. Now I use explicitly open formats and maintain my ability to change software.
