v12.375 making you license more URLs?

I see in the latest release notes the following:

OpManager: From now, users can only monitor upto 5 URLs without having to purchase a license. If more than 5, a separate "URL add-on license" has to be obtained based on the number of URLs you wish to monitor.

So a basic function that has been used for years without a license will now require a license unless you never upgrade y our OpManager version?  What kind of bait-and-switch is that?  We have a couple hundred URL monitors configured in OpManager.
