This a non-evolving way of thinking, the subject of the discussion is oriented on the fact that BAS is an automation tool which should accurately replicate the characteristics of a real browser, we simply observe that one of the functions of BAS (user -agent) does not react as it should, it doesn't matter if f.vision gives a fake also with real Chrome, the fact that we have different results on all other browsers shows that something is not working as it should be, it is undeniable
in a large scale production environment, having the ability to only one kind of user-agent is simply impossible.
You can do a test with our dear friend google with Recaptcha API (recaptcha__en.js), which unfortunately gives a poor score to BAS whit any user-agent other than edge :
https://recaptcha-demo.appspot.com/recaptcha-v3-request-scores.php
Whit a real browser whit get 0.7
Whit base wee get 0.1:

This low score surely does not come only because of a possible (or not...) problem of user-agent whit BAS, but it is certainly part of it ...
the same test with BAS and an EDGE User-Agent we get a better score, 0.3 .... :

f.vision is therefore not false, only the User-Agent of edge which are not detect whit BAS for the moment ...
thank you
