Firstly, thanks for providing/maintaining a great service and API!

I don't recall seeing it before, but now on https://www.themoviedb.org/subscribe I see an option for a Commercial API subscription at $149 / month for projects with < $1M annual revenue and < 2M users.

I currently run a small non-commercial web site (using TMDB API) as a hobby project, but I am thinking to put some ads to offset hosting costs at least. If I do that, do I immediately need to switch to a commercial subscription?

Or is there a lower threshold on the revenue (say $149 / month) before I need to switch, so that I can start paying only once I break even?

Also, is there any difference in availability / performance for a Commercial API subscription vs. the free?

Edit: I have previously seen old posts indicating that ads are fine, I just wanted to confirm it again, now that I saw this Commercial upgrade available.
