That's only a way to avoid getting sued by privacy trolls. Other trolls will still find a way to sue you. Once you are majorly successful, you will get sued regularly. Period.
I think reasonable people could debate both of those points. Making either ethical judgements or PR/branding decisions based only on the minimal standards required of you by law is always a dangerous path to tread.
This is only partly for the reason you give, that some people will sue you now. It's also partly because of the other consequences. Some people may sue you later and with more success, possibly after the rules of the game have been changed by subsequent legislation or precedents. Worse, some people may not bother suing you at all and may simply vote with their wallet and/or encourage others to do so, and that is an attack against which a business is given little opportunity to defend itself.
