This is a very recent development and at present it is difficult to say what, if anything, the ‘victims’ may be entitled to. Saying that, lawsuits have already been filed and users like yourself have started the ball rolling. However, this is an unprecedented case so it would be best advisable to wait and see how it develops before deciding on what to do.
As with any similar claims, it is best done as a class action, meaning you get together with many others in the same position as you and do a group claim. For example of one, see here:
You will see the details of the lawyers dealing with this at the bottom and you may wish to consider contacting them to see if they are willing to take on further clients to include in the class action. Also you will see the claim has been made in the US, so to pursue this individually will probably be quite complex and expensive but if you had a group claim, dealt with by one set of lawyers, it means they will do all the work for all of you at the same time, rather than you having to struggle through it individually.
