I see two approaches that you can take.
- instead of focusing on what you are taking away. Focus on what you can do with the money instead. Telling them that they can have a new TV with that money is a lot more motivation to say yes than taking something away.
- Do the scream test. Just cancel everything and wait for someone to scream about not having a services and resubscribe. Repeat every 6 months or so.
Low latency matters a lot more than bandwidth in any game that isn't turn based.
