This wouldn't be much of a problem for hobbyists if this was 240 per day or 1680 per week, but hitting 10 is easy.
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.
