Good callout to make sure people are aware.

This change is totally fair from my perspective. I see the "always free" as "you will never pay for this for as long as you keep it" as opposed to "this will always be available, and free". People who use free services like this should generally be aware that they are likely to go away or be reduced at some point. I got hit by this with PlanetScale and had to move my stuff to a self-hosted postgres.
