To change or not to change…

Once in a while I’m receiving notifications in order to approve the new therms and conditions of a well known search engine. This in not so bothering to me but what is bothering is the way they do it. Is so tricky and pervert. They don’t say what exactly they changed and they don’t say that they change it 🙂 but they let you know that they change it. So…what is status? Have they changed something? There is an historical with all changes in past 10 years?
And what I like is that they call it a “privacy reminder”. This means that they have done something to my privacy rights but they don’t say what and they just remind me that something is not OK and I should read….
