I can only comment from experience.
The Pi application seems to be heavily geared up for developer advantage. At what cost? Users run the risk of investing time, resource, effort and personal data with no guarantee that they will even be able to claim the coins that they have mined.
For example, the Pi network is 5 years old and yet still offers very little support. Users must verify their phone number to be able to claim the coins that they have mined. However, a number of users are finding that when setting up, their phone numbers were not correct in the first place, with maybe one digit being different. There is no setting that allows users to correct incorrect phone numbers. Could be an innocent mistake couldn't it? But how many times have you input an incorrect phone number on applications? Not many right? Then why are so many Pi users allegedly doing it? The one thing that could prevent you from claiming your coins is the one thing that isn't supported.
This issue also raises legal and privacy concerns that the company don't seem to be taking very seriously. They are knowingly using and storing phone numbers (the incorrect ones) that don't even belong to their users.
Does this put most people off? Probably not.
However. When judging a company like this , I always say, if it was your money that you were spending, would you be happy?
