The missing context here (I think) is that California passed a law saying that digital storefronts (like steam and gog) can’t say things like “buy game” because you aren’t actually gaining ownership of the game, but instead just buying a license to access it. Some people were questioning if this law should apply to gog since their games are drm free and can be freely installed on any compatible devices once you download the installer.
I think some people sabotage relationships for the same reason they throw video games. They have fears/suspicions that it’s going to not work out, and rather than be a victim they want to have some control over the outcome. A loss or failed relationship doesn’t hurt as bad if they caused it to end the way it did.
However in your case, it sounds more like a fear of something different. It’s a lot easier to keep things like they are, when a relationship gets too serious or life impacting it can be easy to be scared of the change, and instead subconsciously decide you want to keep things like they are.
