Perhaps worth it in this situation, but isn't that basically paying protection money? "Nice domain you've got there. Shame if anything happened to it."
If you are using their services for something important you should pay for it. I use fastmail not gmail for this reason: email is too important for me to risk on an account I don't pay for. I don't pay for youtube, because I don't care if they go out of business. I probably would pay for facebook if possible (but only if they make it FACEbook - not political memes, offensive jokes, and cat pictures) as it is a good way to keep in touch with distant friends.
