I would, but I'm like others here who rotate streaming services. I'm only going to sub it for a few months to squeeze in what I need, then cancel the sub and move on, so an extra $5 to $15 isn't really going to phase me. However, I have streaming services lined up for the time being, so I won't resub to AA until 2023, or perhaps even 2024 until more key shows get new seasons (See got its next season, but also waiting for Central Park and Foundation).
However, this would be fairly bad for those who are more price conscious. If Apple gets more content, then perhaps. But as is and as nice a value as ATV+ is, I reckon there wouldn't be too many takers since ATV+ still needs to compete with other ss (Streaming services), and many others happily pay x2 to x4 more since the value, quality, and content there can match what ATV+ has (not unlike how some here on MR pay more for iPhones, and much more for MacOS computers when some of them could easily make do with Windows or Chromebook). If they rotate ss like some of us (or are otherwise saving money and/or constrained by time), that's another battle to fight.
Another thing is there may be many subs to ATV+ if it were $10/mo, but some of those would be from free trials, and as part of Apple One where it's just cheaper for them to sub to that anyways for other Apple services (assuming A1 didn't up their rates as well).
