Make sure you care, it's your money that is in the wallet, if that wallet provider is not reputable, please avoid using it, that's the way to protect your coins.
People do care, but they trust different things. Some of us trust only ourselves, which is the whole concept behind Bitcoin but NOT unfortunately the whole concept behind 90% of crypto that requires you to trust them, the company or the issuer. And to be fair, if I couldn't trust myself and my knowledge of bitcoin I'd probably also want someone else to keep my coins for me. Hence why people go to seek out wallets they feel can take care of their funds for them.
Thus being said I hope there will be more ease in learning new about crypto.
It still is a hard concept to understand (and to explain) for most of the people.
If more people would understand what crypto really is - there will be less users of centralized /online hot wallets for sure.
