Yes, so annoying. Some shows just makes you interested, invested in the story, you learn the characters' names... Then the season ends, you look up when the next season comes out... And you see that the show has been canceled... Happened too many times, last one that really frustrated me was GLOW.

I wonder if it has a vicious circle, spiral component to it, like how Google keeps killing their products because people don't adapt them, because Google keeps killing their products.

Some percentage of users don't trust Netflix anymore and don't start watching a series until they know it has an ending. A new show launches, it doesn't perform too well, so Netflix cancels it after the second season. Now, the people who enjoyed the show will be more sceptical of new shows, and now a larger percentage of users will "boycott" new shows.
