My personal reasons for this are
- Privacy = Not sending data to google
- It is the most annoying captcha (even if you’re doing it correct you’re doing it wrong)
- There are already enough open source solutions out there that could be used easily instead
Also, here’s other peoples opinion:

If I can do this myself with a pull request or anything; where? wait a sec, I need to solve the captcha for this…
