@UniSuperBox
Thank you so much for removing ReCaptcha!

I read here since more than 6 months but when I saw ReCaptcha I did abort the registration at the forum. ReCaptcha is really terrible and I also try to avoid Google services. I am still not happy about Akismet but willing to accept it which is the reason why I did now finish the registration.

It is very exiting and awesome to see what happens at UBports to get the choice not to use Android or IOS and get back some privacy.

I've turned off ReCaptcha on the registration page, and we'll need to wait for the forum to reload for it to take effect. We'll see if it has any effect on the spam registrations on the forum (right now we have at least one per day).

I'm a moderator on the Linux Mint forum. We get lot more spam than that; we deal with that by eyeballing (human moderators, well... some users have their doubt about the 'human' part ) But we can handle that because we probably have a larger mod team.
We also get more traffic.

To conclude, as explained by @Flohack who is not European, he do with an UT phone, but he also already can't do without an Androîd phone anymore: I don't know if it's love for the last !

To correct you, Florian is very much a European, Austria is an EU member. I believe he uses android for certain apps only, Car sharing being one, possibly banking. Some companies only cater to android or iOS users, sometimes it's easier to just by a cheap android phone to be able to use those services than to purposely make your own life just that bit harder.

Concretely, the sending of validation code by sms in the long term being doomed to disappear, banks will have to use biometric recognition of their customers or to have their customers log on to the bank's mobile app (I also think that the biometric recognition system is on the bank's mobile app). I don't know if a bank's biometric recognition can be done outside the application, i.e. on a simple web page of the bank.

Clearly it should eventually be impossible for some operations to do without google ''services'' because they are used in the android or ios applications of banks. This should force everyone to use an android or ios phone and make it impossible to do without the GAFA !!!

UT will have to quickly develop biometric recognition (this should I think be operational faster for the Volla phone) but this may not be enough.

To overcome the intrusion of googles services, Lineage os uses MicroG. I don't know if this could be implemented under UT as part of a functional Anbox. And even if it were possible, if it could make banking applications usable.

why do I still see them

Because, just like Amazon and Microsoft, a significant amount of infrastructure relies on them. There is no total escape from any of them, if you want to live in modern society and use the Internet.
