It's not phrased as a usage cut, but rather when their 50% higher limits ends.
EDIT: its 33.3% less usage after July 13th
That’s not a cut? They gave you extra usage for a set time period, it was never part of your subscription.
Huh, it's wild that they didn't send an email about this. I can't imagine people taking this well, especially as they don't seem to be giving notice about the end of it either.
