Ironically, it's the paid rates that are being reduced more (though they don't have hourly limits still, so more flexibility, but the fair use thing might come up), as they were infinite previously, now Pro is 34 pulls/hour (on average, which is less than authenticated), Team is 138 pulls/hour (or 4 times Pro) and Business 1380 pulls/hour (40 times pro, 10 times team).
My feeling this is trying to get more people to create docker accounts, so the upsell can be more targeted.
