Not really the same. They switched from a proprietary platform to a free platform. That is a much larger jump than simply switching proprietary platforms with much larger costs and gains. They wanted control and switched to get it, whereas you just swapped out landlords.
So first of all, I don’t think it’s true that the article describes a switch to 100% free software. For example, the author bought a mirrorless camera, which is going to run proprietary software. Second, and more importantly, I think your comment implies that the only lever of control is switching between free and non free software and I don’t agree with this. For example, I am now protected against Google terminating or otherwise locking me out of my account whereas I was not previously protected. Even though I disagree with your comment, I appreciate that free software has some advantages over proprietary software and I would not dispute the claim in general.
