Yes, it would be too late for you, but it would also be too late for the CA in this story, since the purpose of these technologies is to create and preserve a "smoking gun" and now everybody can see they aren't trustworthy.
In most countries, law enforcement are disinclined to use tools that will only work once - because what if they need that tool tomorrow for something more important? So this provides you with a bit of herd immunity, there is probably someone doing something naughtier than you who would be a better target.
It is also legally easier to get away with demanding that somebody do something they already _can_ do than to demand they come up with a way to do something they can't already do. British courts for example asked Internet Service Providers "Do you have a way to block web sites, e.g. for having child pornography on them?" and all the big ISPs said "Oh yes, we have that" and then the courts said "Aha. OK, then you must use that to also block copyright infringements, Hollywood will tell you what to block". But for the tiny ISPs like mine that said "No, we just move bits - nazis, child porn, bomb making, if it's illegal then you should convict the people doing it, not our problem" the courts said "Then it would be outrageous for us to demand you do as Hollywood asks, carry on as you were".
Because CT logging is mandated by Google, most CAs are building systems that automatically log everything. So then "Issue this but don't log it" becomes a huge ask, the front line guy the secret police get to says "I don't have a way to do that, it always logs everything" and that increases the chance the spooks get forwarded to an executive who says "Woah, this suicides my whole company, you better get yourselves a warrant, and I am calling my lawyer right now".
