Why it is here

ChatGPT launched as a free research preview on November 30, 2022. OpenAI invited people to try it and share feedback, using the public release to learn about the system’s strengths and weaknesses. — OpenAI
Keep in mind
Main complaint: a Plus user reports no warning when memory is full and no usage bar. ChatGPT still confirms new entries as saved, so you can't tell when to clean up.
Users also report ChatGPT saying "Memory updated" while the entry does not show up in the saved-memories list. This matches the ranking's warning that the list may not show everything.
