@Petzi-Port because the company is not trustworthy. They promised that no customer data would be stored. A few years ago, the database with all customer data was leaked => promise broken and the whole world knows the addresses of people with crypto. Then the introduction of the recovery feature. If the seed can be exported via a software update, then also via malware. The third reason for me is that I don't want to worry about my coins with a hardware wallet. I had some shitcoin on the ledger a few years ago and didn't bother with it for a year. Looked at it again after a year and zap, the support for the Shitcoin was discontinued half a year ago without being informed. The coins were lost forever.
