I had an App on my phone to manage all of my loyalty cards. It worked great, it was cheap and I never had an issue with it. Because it worked well, a lot of people used it. Then LifeLock bought it. Suddenly, I am barraged by offers and ads from LifeLock asking me to sign up for their services, promising to "secure and protect" my data. After a few weeks, LifeLock announces that it has been hacked and that they deleted all of my data and shut down the app. After that display of their complete lack of security, they keep sending me notices asking to sign up. Not bloody likely, and thanks for ruining my App!
Then one of my financial Apps get bought by Intuit, and it is now ruined. And then another announces that it was bought by Yahoo, and Yahoo has decided to re-assign the developers and shut down the App. Arrrggghhh!
I wish big corporations would continue to support Apps after they buy them! Or developers would refuse the money waved in their face and try to be the next Sergy Brin or Elon Musk!
