Well, that's why I refuse to (personally) use any software that comes with any kind of "fuel"* that needs to be "topped up" periodically even if it insists it's free and will always be available. It's just voluntarily putting on a collar with a leash somebody else is free to tug on** any time.
* actual real-world example.
