I've left whatsapp and google behind recently, and the experience has been insightful.
When leaving whatsapp, I tried to make a backup of my conversations, but that required a slow manual manipulation to be performed for each conversation one by one on mobile. It's like they don't want you to do that.
When leaving google photo, there was no way to delete my 40k photos in one go, only a laggy "scroll, select, delete, repeat" manual process.
In google maps, my takeout of all the map pins was inexplicably unusable. They gave me a csv full of web links to google map, that even gemini didn't know what to make out of. Some people made a business out of the shortcomings of that tool.
In tech, I've ofen seen a combination of "are you really sure ?" dark patterns and buggy, low effort takeout options.
In real life, things get more personal. The gym suddenly treats you like a dog for cancelling your membership. They don't return your calls. The bank hides behind the fine lines of the contract. Everyone needs an expensive snail mail request for everything they don't want to do. All the sweet talk evaporates.
For some companies, it's the opposite, they only start caring about you when you churn. You telephone rate suddenly goes cheaper. You natural gas price inexplicably gets slashed in half. They go from treating you like an anonymous excel line to a VIP.
All that to say, if you're not sure about investing more into a company, try to leave and see how that goes. Often you'll get to see their true face, or get a nice discount.
