Here are some ideas: Proactive compensation, an apology letter, hosting an AMA live stream, and a postmortem on how this misleading messaging made it out in the first place.
I don't think you can get damages for what might happen in the future, only for real damages and probably only this activist that had his IP disclosed can prove damages.
Probably the best you could hope for would be to get out of a long term contract "I paid for a 2 year term based on promises that weren't true"
Otherwise, your best recourse to prevent your IP from being disclosed in the future is to find a provider that won't disclose it under any circumstances (probably not possible), or hide your IP yourself.
