@Pumpkincozynights you are right that their actions have tarnished the reputation of the sector but I don’t follow your logic…
The money raised by the walk went directly to a big charity - NHS Charities Together. The subsequent scandal is nothing to do with them. The issue was how the charity his daughter set up was using money intended for charitable purposes, and her activities outside of that charity (e.g. letting people think proceeds from sales of the book was going to charity). The charity commission rules exist to stop people like this from setting up or running charities and in this case has done its job.
Her actions should make us more vigilant and aware but should not stop us from donating to charities that are doing good work.
And generally, I would say that buying goods (like a book) where a % ‘goes to charity’ is a poor way of giving. Those sorts of deals can raise funds and awareness of a cause so I’m not knocking these sorts of charity partnerships but they are often more about marketing and PR than charity.
Personally I think if you want to donate, choose a charity that is doing the work that you feel is important and trust them to use it wisely. If you want to help find a cure for cancer, or achieve world peace, donate to a big charity that knows what it’s doing. You are unlikely to be able to find a small, local charity with minimal overheads that can do that. On the other hand, if you want to help local people who are going hungry, you can donate to a local food bank. There is room and need for both.
