Okay, so I can explains to some of Your concerns:

• they did research and it seems that 77% of people are ready to share their anonymized medical data for research even for free, they just don't have the possibility now or it is very hard and annoying. The token is to persuade another 23% who dont want to do it for free. Giving crypto wallet address would be optional and old people who are not into crypto, will be able to do it for free or they can give wallet of their younger grandchilds or charity organisations etc. In Poland people who give blood, obtain energy drinks and chocolates. They cannot pay fiat money for medical data, but they can pay crypto. Tokens will be a "reward" just like energy drinks and chocolates.
• they are talking with hospitals and it will work like - patient gives consent, and hospital sends data to Data Lake. No problem with that.
• of course I cannot guarantee that data will be anonymized properly, but when I think about it, I know that medical companies need the biggest amount of data, not personalized data. You don't find a cure for cancer by knowing what is the patient's name or address or job, the only thing they need is as much data as possible and it gives completely nothing to them to have data with personal informations. They will not be interested in paying extra for something they completely dont need. And 99% of people giving that argument are using Facebook, Google, Apple and other software which knows anything about them and they give their data for free and see no problem with that... And data will not be sold to insurance companies and similar ones.
• when it comes to the team, I think they are great. They focus on facts and developing project, not on fluffy marketing and CEX listings. The Founders are attending like 2-3 conferences every week and more important - this is the only project they are working on, they are not running a few simultaneously.

Is 20% too much for the team? I cannot answer that question. But it seems like the project is hiring people who are believing in it, not the ones who only want to earn a lot of money.
