I've been caught by this change. Google have requested that my app be audited by one of the suggested security firms. The lowest quote I have right now is $22k.<p>We're a bootstrapped business with nowhere near this kind of cash, so this effectively means Google are shutting our service down.<p>What's crazy is that while this might help protect from negligent developers accidentally losing a few user keys, it doesn't really solve the real problems like it's claiming to. It in no way protects you from the worst offenders, the Cambridge Analytica's out there, the ones with plenty of cash, from still stealing or abusing your data. They can just pay to make this go away.<p>This is seriously bad news for any independent developers or small companies who are building apps on top of Google's API.
